Submission guidelines

Online submission

All submissions must be made via our online submission system. Using this system, authors can upload manuscript files (text, figures, videos) directly to our office and check on the status of their manuscripts during the review process. In addition, reviewers can access the manuscript online, which speeds up the review process. Revised manuscripts should be uploaded via the link provided in the editor's decision letter. Please do not submit revisions as new manuscripts.

Before a manuscript is submitted, please review our editorial policies, and ensure that the submission complies with our policy requirements.

Large Language Models (LLMs), such as ChatGPT, do not currently satisfy our authorship criteria. Notably an attribution of authorship carries with it accountability for the work, which cannot be effectively applied to LLMs. Use of an LLM should be properly documented in the Methods section (and if a Methods section is not available, in a suitable alternative part) of the manuscript. In response to emerging information, advice, guidance and policy around artificial intelligence (AI), we have created a dedicated AI section in our Editorial Policy page. Please familiarize yourself with this content and comply with relevant policies.

We encourage all authors to register for an ORCID iD (ORCiD) and include their ORCiD in their author profile at or before manuscript submission. For more details on Springer Nature’s support of ORCiD, please follow this link.
 

Submission policies

Submission to Communications Chemistry is taken to imply that there is no significant overlap between the submitted manuscript and any other papers from the same authors under consideration or in press elsewhere. (Novelty is not compromised by either abstracts or unrefereed web preprints). The authors must include copies of all related manuscripts with any overlap in authorship that are under consideration or in press elsewhere. If a related manuscript is submitted elsewhere while the manuscript is under consideration at Communications Chemistry, a copy of the related manuscript must be sent to the editor.

The primary affiliation for each author should be the institution where the majority of their work was done. If an author has subsequently moved, the current address may also be stated.

If the manuscript includes personal communications, please provide a written statement of permission from any person who is quoted. E-mail permission messages are acceptable.

Follow this link for further information on the review process and how editors make decisions.

After acceptance, changes to the manuscript may be made so that papers conform to our style. The corresponding author is sent proofs and is welcome to discuss changes with the editors, but Communications Chemistry reserves the right to make the final decision about matters of style and the size of figures.

The editors also reserve the right to reject a paper even after it has been accepted if it becomes apparent that there are serious problems with the scientific content or with violations of our publishing policies.
 

Costs

Communications Chemistry does not charge submission fees or page charges. However, authors submitting to Communications Chemistry are required to publish their work open access, through payment of an article processing charge (APC), in the case of eventual acceptance.

Please see the pages on open access and article processing charges for APC pricing and details of our free funding support service.
 

General information for preparing manuscripts

This guide outlines key points for preparing primary research manuscripts for submission to Communications Chemistry.

The corresponding author should be familiar with the journal’s editorial policies and is solely responsible for communicating with the journal and managing communication between coauthors. Before submission, the corresponding author ensures that all authors are included in the author list and agree with its order, and that they are aware the manuscript is to be submitted. 

If you wish to participate in double-anonymized peer review, please prepare your manuscript in a way that conceals the identities of all the authors and tick the appropriate box during online submission. We recommend that authors refer to our double-anonymized peer review guidelines when preparing a double-anonymized peer review manuscript. Please note that editors do not ensure that the paper is properly anonymised; that is the responsibility of the authors.
 

Cover letter

Authors should provide a cover letter that includes the affiliation and contact information for the corresponding author. The cover letter is an excellent opportunity to briefly discuss the context and importance of the submitted work and why it is appropriate for the journal. Please avoid repeating information that is already present in the abstract and introduction. The cover letter is not shared with the referees, and should be used to provide confidential information, such as conflicts of interest, and to declare any related work that is in press or submitted elsewhere.

It is also appropriate to include suggested or excluded referees in the cover letter. We strive to ensure that the diversity of our reviewers reflects that of the broad scientific community, in terms of gender, ethnicity/race, geographic location, and career stage. We ask that you keep this in mind when suggesting potential referees.

Due to our policy on transparent peer review, you must clearly state in your cover letter whether you wish to opt in or opt out of the publication of the reviewer reports when submitting the final version of your manuscript for publication.
 

Format of manuscripts

Manuscripts submitted to Communications Chemistry do not need to adhere to our formatting requirements at the point of initial submission; formatting requirements only apply at the time of acceptance. For a detailed breakdown of our formatting requirements for primary research manuscripts, and for clarity on recommended structure and content, please see our style and formatting guide. A style and formatting checklist is also available as a resource. For information on formatting non-primary research manuscripts, please consult the page on Communications Chemistry content types.

We encourage authors to incorporate the manuscript text and figures into a single PDF or Microsoft Word file. Suitably high resolution figures may be inserted within the text at appropriate positions or grouped at the end. Each figure legend should be presented on the same page as its figure. We can accept LaTeX files at the acceptance stage, but before then please supply compiled PDFs.

Manuscripts published in Communications Chemistry are not subject to in-depth copy editing as part of the production process. Authors are encouraged to seek copy editing or language editing services for their manuscripts, either before submission, or at the revision stage, should they feel it would benefit their manuscript. Such services include those provided by our affiliates Nature Research Editing Service and American Journal Experts. Please note that the use of Nature Research Editing Service is at the author's own expense and in no way implies that the article will be selected for peer review or accepted for publication.
 

Methods

Authors must ensure that their Methods section includes adequate experimental and characterization data necessary for others in the field to reproduce their work. Descriptions of standard protocols and experimental procedures should be given. Commercial suppliers of reagents or instrumentation should be identified. Sources for kits should be identified. Experimental protocols that describe the synthesis of compounds should be included. Authors should describe the experimental protocol in detail, referring to amounts of reagents in parentheses, when possible (e.g. 1.03 g, 0.100 mmol). Standard abbreviations for reagents and solvents are encouraged. Safety hazards posed by reagents or protocols should be identified clearly. Isolated mass and percent yields should be reported at the end of each protocol.

Acknowledgements

Acknowledgements should be brief and should not include effusive comments. Assistance from proof-readers and editors not affiliated with the journal should also be acknowledged here.

Funding information should be placed in the Acknowledgement section. When declaring funding, our recommended best practice is that authors should acknowledge funders and grants on publications when the activities that contributed to that publication are within scope of the acknowledged grant and arise directly from a specific grant. An appropriate format for acknowledgement of grant funding is: A.B.C. discloses support for the research of this work from Funder [grant number xxxx], Funder [grant number xxxx] and Funder [grant number xxxx]. D.E.F. discloses support for publication of this work from Funder [grant number xxxx], Funder [grant number xxxx] and Funder [grant number xxxx].

 

Author contributions

Communications Chemistry requires an Author Contribution Statement that specifies the individual contributions of each co-author. 

Authorship provides credit for a researcher's contributions to a study and carries accountability. Guidance and criteria for authorship can be found in our editorial policies. The individual contributions of authors to the manuscript should be specified in this section, as well as any equal contributions or shared supervision.  Please use initials to refer to each author's contribution in this section. For example: "A.P.M. 'contributed' Y and Z; B.T.R. 'contributed' Y," etc.
 

Competing interests

A competing interests statement is required for all accepted papers published in Communications Chemistry. If there is no conflict of interest, a statement declaring this will still be included in the paper.

In the interests of transparency and to help readers form their own judgements of potential bias, Nature Portfolio journals' require authors to declare any competing financial and/or non-financial interests in relation to the work described. The corresponding author is responsible for submitting a mandatory, signed, competing interests' statement on behalf of all authors of the paper upon submission. Competing interests are defined as financial and non-financial interests that could directly undermine, or be perceived to undermine the objectivity, integrity and value of a publication, through a potential influence on the judgements and actions of authors with regard to objective data presentation, analysis and interpretation. Please read the full policy for guidance, which gives more information on how competing interests are defined and how it applies to authors, peer reviewers, editors, external editors and editorial board members. All such interests have to be declared and if no such interest exists, this must also be declared upon submission.

 

Data availability

An inherent principle of publication is that others should be able to replicate and build upon the authors' published claims. Please note that all published manuscripts reporting original research in Nature Portfolio journals must include a data availability statement. The data availability statement must make the conditions of access to the “minimum dataset” that are necessary to interpret, verify and extend the research in the article, transparent to readers. This statement must be submitted with your manuscript. Please see the full policy for more information. Authors who need help understanding our data sharing policies, help finding a suitable data repository, or help organizing and sharing research data can access Springer Nature’s Author Support portal for additional guidance.

Communications Chemistry advocates for the complete and transparent reporting of research. Please see our policies here and here for further information regarding our reporting requirements.
 

Computer code

Any previously unreported custom computer code used to generate results reported in the manuscript that are central to the main claims must be made available to editors and referees upon submission. Any practical issues preventing code sharing will be evaluated by the editors who reserve the right to decline the manuscript if important code is unavailable. At publication, Nature Portfolio journals consider it best practice to release custom computer code in a way that allows readers to repeat the published results. Where availability of custom computer code is deemed to be central to our editorial interest in the paper and the reader’s ability to make use of and reproduce the work, we may decline to review or publish the manuscript if authors indicate that they would be unable to release the computer code upon publication.

For all studies using custom code that is deemed central to the conclusions, a statement must be included in the Methods section, under the heading "Code availability", indicating whether and how the code can be accessed, including any restrictions. See the section on Availability and peer review of computer code in our Editorial Policies for more information.
 

Supplementary Information

Any Supplementary Information should be submitted with the manuscript and will be sent to referees during peer review. It is published online with accepted manuscripts. We request that authors avoid "data not shown" statements and instead make their data available via deposition in a public repository (see Reporting standards and availability of data, materials, code and protocols for more information). Any data necessary to evaluate the claims of the paper that are not available via a public depository should be provided as Supplementary Information. 

Supplementary Information is not edited, typeset or proofed, so authors should ensure that it is clearly and succinctly presented at initial submission, and that the style and terminology conform to the rest of the paper. See our style and formatting guide for details on how the Supplementary Information should be formatted. Please note that modification of Supplementary Information after the paper is published requires a formal correction, so authors are encouraged to check their Supplementary Information carefully before submitting the final version.

Further queries about submission and preparation of Supplementary Information should be directed to email: commschem@nature.com
 

It is a requirement of submission that you alert us to any related manuscripts with overlapping authorship that are under consideration (including under appeal) or in press at other journals (see our editorial policies on duplicate submissions for details). Copies of these manuscripts should be clearly marked and included as separate files with your submission. Abstracts or other unrefereed preprints do not compromise novelty.
 

General figure guidelines

Authors are responsible for obtaining permission to publish any figures or illustrations that are protected by copyright, including figures published elsewhere and pictures taken by professional photographers. The journal cannot publish images downloaded from the internet without appropriate permission.

Unnecessary figures should be avoided: data presented in small tables or histograms, for instance, can generally be stated briefly in the text instead. Figures should not contain more than one panel unless the parts are logically connected; each panel of a multipart figure should be sized so that the whole figure can be reduced by the same amount and reproduced at the smallest size at which essential details are visible.

Should your manuscript be accepted, you will receive more extensive instructions for final submission of display items. However, some guidelines for final figure preparation are included below if you wish to minimize later revisions and possible delays.

Figures should be numbered separately with Arabic numerals in the order of occurrence in the text of the manuscript. When appropriate, figures should include error bars. A description of the statistical treatment of error analysis should be included in the figure legend. Please note that schemes are not used; sequences of chemical reactions or experimental procedures should be submitted as figures, with appropriate captions. A limited number of uncaptioned graphics depicting chemical structures—each labelled with their name, by a defined abbreviation, or by the bold Arabic numeral—may be included in a manuscript.

Figure lettering should be in a clear, sans-serif typeface (for example, Helvetica); the same typeface in the same font size should be used for all figures in a paper. Use 'symbols' font for Greek letters. All display items should be on a white background, and should avoid excessive boxing, unnecessary colour, spurious decorative effects (such as three-dimensional 'skyscraper' histograms) and highly pixelated computer drawings. The vertical axis of histograms should not be truncated to exaggerate small differences. Labelling must be of sufficient size and contrast to be readable, even after appropriate reduction. The thinnest lines in the final figure should be no smaller than one point wide. Authors will see a proof that will include figures.

Figures divided into parts should be labelled with a lower-case bold a, b, and so on, in the same type size as used elsewhere in the figure. Lettering in figures should be in lower-case type, with only the first letter of each label capitalized. Units should have a single space between the number and the unit, and follow SI nomenclature (for example, ms rather than msec) or the nomenclature common to a particular field. Thousands should be separated by commas (1,000). Unusual units or abbreviations should be spelled out in full or defined in the legend. Scale bars should be used rather than magnification factors, with the length of the bar defined. In legends, please use verbal explanations such as "open red triangles" rather than visual cues.
 

Figures for peer review

At the initial submission stage authors should incorporate figures into the main article file, ensuring that any inserted figures are of sufficient quality to be clearly legible. If this is not possible in a combined manuscript file, authors should either submit separate high resolution figure files or deposit image data in a suitable repository (e.g. figshare) and use their option to provide a private sharing link for the referees to access it.

When submitting a final manuscript for publication, all figures must be uploaded as separate figure files ensuring that the image quality and formatting conforms to the specifications below.
 

Figures for publication

Each complete figure must be supplied as a separate file upload. Multi-part/panel figures must be prepared and arranged as a single image file (including all sub-parts; a, b, c, etc.). Please do not upload each panel individually.

Please read the digital images integrity and standards section of our editorial policies. When possible, we prefer to use original digital figures to ensure the highest-quality reproduction in the journal. For optimal results, prepare figures to fit A4 page-width. When creating and submitting digital files, please follow the guidelines below. Failure to do so, or to adhere to the following guidelines, can significantly delay publication of your work.

Authors are responsible for obtaining permission to publish any figures or illustrations that are protected by copyright, including figures published elsewhere and pictures taken by professional photographers. The journal cannot publish images downloaded from the internet without appropriate permission.

Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

  • Provide images in RGB color and at 300 dpi or higher resolution.
  • Use the same typeface (Arial or Helvetica) for all figures. Use symbol font for Greek letters.
  • Use distinct colors with comparable visibility and avoid the use of red and green for contrast. Recoloring primary data, such as fluorescence images, to color-safe combinations such as green and magenta or other accessible color palettes is strongly encouraged. Use of the rainbow color scale should be avoided.
  • Figures are best prepared at the size you would expect them to appear in print. At this size, the optimum font size is 8pt.
  • We prefer vector files with editable layers. Acceptable formats are: 
    .ai, .eps, .pdf, .ps and .svg for fully editable vector-based art; layered .psd and .tif for editable layered art; .psd, .tif, .png and .jpg for bitmap images; .ppt if fully editable and without styling effects; ChemDraw (.cdx) for chemical structures.
  • Please refer to the Nature Research style guide for formatting of chemical structures.
     

Characterization of chemical and biomolecular materials

Communications Chemistry is committed to publishing the highest-quality research. Manuscripts submitted to the journal will be held to rigorous standards with respect to experimental methods and characterization of compounds. Authors must provide adequate data to support their assignment of identity, purity and homogeneity for compounds and materials described in the manuscript. Editors and reviewers will be responsible for assessing the completeness of the characterization. Authors should provide a statement confirming the source, identity and purity of known compounds and biomolecules that are central to the scientific study, even if they are purchased or resynthesised using published methods.

Chemical nomenclature and abbreviations

Molecular structures are identified by bold, Arabic numerals assigned in order of presentation in the text. Once identified in the main text or a figure, compounds may be referred to by their name preferably using systematic IUPAC nomenclature, by a defined standard abbreviation, or by the bold Arabic numeral (as long as the compound is referred to consistently as one of these three). Unconventional or specialist abbreviations should be defined at their first occurrence in the text.

Methods section

The Methods section should be written as concisely as possible but should contain all elements necessary to allow interpretation and replication of the results. We encourage the inclusion of specific sections for statistics, reagents and animal models. Experimental protocols that describe the synthesis of compounds must be included. Authors must describe the experimental protocol in detail, referring to amounts of each reagent in parentheses (e.g. 1.03 g, 0.100 mmol). The source for commercial compounds must be provided. Standard abbreviations for reagents and solvents are encouraged. Safety hazards posed by reagents or protocols must be identified clearly. Isolated mass and percent yields should be reported at the end of each protocol. Isomeric ratios of compounds obtained as an inseparable mixture must be quantified where possible. Authors are encouraged to share their step-by-step experimental protocols on a protocol sharing platform of their choice. Nature Portfolio's Protocol Exchange is a free-to-use and open resource for protocols; protocols deposited in Protocol Exchange are citable and can be linked from the published article. More details can be found at www.nature.com/protocolexchange/about.

Chemical identity

Chemical identity for organic and organometallic compounds should be established through spectroscopic analysis. Detailed spectral data for compounds should be provided in list form (see below). Figures containing spectra generally will not be published as a manuscript figure unless the data are directly relevant to the central conclusions of the paper. Example format for compound characterization data:
mp: 100–102 °C (lit.ref 99–101 °C); [α]D = -21.5 (0.1 M in n-hexane); 1H NMR (400 MHz, CDCl3): δ 9.30 (s, 1H), 7.55–7.41 (m, 6H), 5.61 (d, J = 5.5 Hz, 1H), 5.40 (d, J = 5.5 Hz, 1H), 4.93 (m, 1H), 4.20 (q, J = 8.5 Hz, 2H), 2.11 (s, 3H), 1.25 (t, J = 8.5 Hz, 3H); 13C NMR (125 MHz, CDCl3): δ 165.4, 165.0, 140.5, 138.7, 131.5, 129.2, 118.6, 84.2, 75.8, 66.7, 37.9, 20.1; IR (Nujol): 1765 cm-1; UV/Vis: λmax 267 nm; HRMS (m/z): [M]+ calcd. for C20H15Cl2NO5, 420.0406; found, 420.0412; analysis (calcd., found for C20H15Cl2NO5): C (57.16, 57.22), H (3.60, 3.61), Cl (16.87, 16.88), N (3.33, 3.33), O (19.04, 19.09).

Yield and sample purity

Yield and evidence of sample purity is required for each isolated compound. Methods for purity analysis depend on the compound class. For most organic and organometallic compounds, purity may be demonstrated by high-field 1H NMR and 13C NMR data, although elemental analysis (±0.4%) is encouraged. Quantitative analytical methods including chromatographic (GC, HPLC, etc.) or electrophoretic analyses may be used to demonstrate purity for small molecules and polymeric materials. Melting points for crystalline compounds should be reported. In cases where isolation of pure samples is not possible (intermediates, mixtures, unstable species) or where the obtained quantities are not sufficient to perform a full characterization, a statement must be given, indicating that the species were not isolated or fully characterized.

Spectroscopy

See the provision of NMR spectra section below for full details of our requirements for the collection, availability, reporting and presentation of NMR spectra. UV or IR spectral data may be reported for the identification of characteristic functional groups, when appropriate.

Characterization of chiral compounds

The enantiomeric composition of chiral compounds should be characterized using appropriate techniques, including polarimetry, NMR, single crystal XRD, or by correlation of HPLC or GC. The specific rotation should be reported. Composition may be reported as enantiomeric excess or ratio.

Mass spectrometry

Authors should also provide mass spectral data to support molecular weight identity. High-resolution mass spectral (HRMS) data are preferred, and when m/z < 1,000, the calculated and found values should be within 0.003. When m/z > 1000, we expect an experimental value within 1 ppm of the calculated value.

Single-crystal X-ray diffraction

Crystalline solids may be characterized by single crystal XRD. Crystallography should be combined with other techniques as required to establish identity and purity. Manuscripts reporting new structures from crystallographic analysis should be accompanied by a standard crystallographic information file (.cif) and a structural figure with probability ellipsoids should be included in the main supplementary information file. The structure factors for each structure should also be submitted, preferably embedded in the main .cif file, although they may be provided as a separate .hkl and/or .fcf file. Use of the latest version of the program SHELXL, which embeds the structure factors information in the main .cif file, is encouraged. The structure factors and structural output must be checked using IUCr's CheckCIF routine and a PDF copy of the output included with the submission, explaining any A- or B-level alerts. Additionally, an explanation for all A- and B-level alerts must be given in the supplementary information. Crystallographic data for small molecules should be submitted to the Cambridge Structural Database and the deposition number referenced in the manuscript. Full access must be provided on publication. 

Solid state compounds

The homogeneity and purity of solid state compounds may be characterized by solid state NMR, powder X-ray diffraction data and where possible compared to calculated diffraction patterns.

Combinatorial compound libraries

Authors describing the preparation of combinatorial libraries should include standard characterization data for a diverse panel of library components.

Biomolecular identity

For new biopolymeric materials (oligosaccharides, peptides, nucleic acids, etc.), direct structural analysis by NMR spectroscopic methods may not be possible. In these cases, authors must provide evidence of identity based on sequence (when appropriate) and mass spectral characterization.

Biological constructs

Authors should provide sequencing or functional data that validates the identity of their biological constructs (plasmids, fusion proteins, site-directed mutants, etc.) either in the manuscript text, supplementary information, or the Methods section, as appropriate.

Chemical probe data

Manuscripts that report the identification and validation of new chemical probes are encouraged to submit their probes to the Chemical Probe Portal.

Small-molecule high-throughput screening data

Manuscripts reporting high-throughput screens of small-molecule libraries should include a supplementary table summarising the assay, library, screen and post-screen analysis. A template and instructions for preparing the high-throughput screening table are available.

Macromolecular structural data

Manuscripts reporting macromolecular structures should contain a table summarising structural and refinement statistics. Templates for such tables describing cryo-EMNMR and X-ray crystallography data are available. To facilitate assessment of the quality of the structural data, a stereo image of a portion of the electron density map (for crystallography papers) or of the superimposed lowest energy structures (>10; for NMR papers) should be provided with the submitted manuscript. If the reported structure represents a novel overall fold, a stereo image of the entire structure (as a backbone trace) should also be provided. For cryo-EM structures, a representative micrograph showing individual particles should be provided in the submission. Crystallographic data for macromolecules must be submitted to the Worldwide Protein Data Bank (wwPDB), NMR data must be submitted to the Biological Magnetic Resonance Data Bank (BMRB) and cryo-EM data must be submitted to the Electron Microscopy Data Bank (EMDB). Deposition numbers must be referenced in the data availability statement in the manuscript. Full access must be provided on publication.

Microscopy

Microscopy images should be representative of the wider sample and labelled with scale bars. Full details for the reporting of microscopy experiments can be found on our policy page

Computational results

When electronic structure calculations are reported in the manuscript, the atomic coordinates of the optimised computational models should be provided. Codes and software should be available and properly referenced in the article and/or supplementary information. Input parameters, basis sets and coordinates of the input and output structures must be reported. If relative energies are reported, absolute energies should be provided in the supplementary information. For molecular dynamics trajectories, at least the initial and final configurations should be supplied. We encourage you to make them available by uploading the structures in any of the existing data repositories (see e.g. https://www.nature.com/sdata/policies/repositories). Alternatively, they can be supplied as a separate supplementary data file (ideally as a plain, unformatted text file).
 

Provision of NMR spectra

Availability

  • Copies of NMR spectra should be provided for all new and known compounds. Spectra should be provided in a Supplementary Data file, separate from the main Supplementary Information PDF.

Nuclides

  • 1H NMR spectra are essential.
  • 13C{1H} NMR spectra are essential.
  • 19F and/or 19F{1H} NMR spectra are essential for fluorine-containing molecules.
  • 31P and/or 31P{1H} NMR spectra are essential for phosphorus-containing molecules.
  • 1D NMR spectra for other nuclides, proton decoupled or otherwise, are encouraged for molecules that contain e.g. 7Li, 11B, 77Se, etc.
  • 2D experiments should be used where necessary to confirm the identity of the compound.

Reporting

  • It must be made clear for each nuclide, for each compound, whether decoupling was applied during the acquisition or not (e.g. 31P versus 31P{1H})
  • It must be ensured that the frequency reported for each experiment is correct for the instrument and nuclide, noting that different nuclides on the same instrument will have different frequencies.
  • The probe temperature must be listed when it is accurately known.
  • The solvent and standard used must be listed, alongside indicated solvent or peak suppression protocols used in data acquisition.
  • 1H NMR chemical shifts should be given to two decimal places, and 13C NMR chemical shifts to one decimal place (unless an additional decimal place will help to distinguish overlapping peaks).
  • All coupling constants must be reported, and the total number of signals must match the number expected.
  • The number of bonds for scalar coupling constants should be indicated where this is known, e.g. 2J, 3J, etc.
  • If a signal is assigned as a multiplet, it must be assigned a chemical shift range; if the signal has a well-defined first order scalar coupling pattern its chemical shift must be quoted as the centre of the pattern.
  • Only accepted abbreviations for multiplicities and descriptors should be used.

Presentation

  • NMR spectra should be presented as one spectrum per A4 page, in landscape format.
  • It is not acceptable to edit the spectra for any reason.
  • Each spectrum should be labelled with the compound number and/or structure, the nuclide, the solvent and the field strength.
  • Each 1D spectrum should be scaled so that the largest peak for the analyte (not the solvent peak) reaches the top of the spectrum.
  • Each 13C{1H} NMR spectrum should be scaled so that the solvent signal reaches the top of the spectrum; the signal/noise ratio must be sufficient that all signals are clearly resolved from the baseline.
  • All peaks must be picked and labelled and the font should be clear and large enough to read.
  • All peaks on 1H NMR spectra must be integrated such that the integral of each signal corresponds (at least approximately) to the number of protons that it represents.
  • The line thickness for each spectrum should be sufficiently clear to allow the coupling pattern to be identified; insets should be used to show complex coupling patterns that are not clear from the full page spectrum.
  • 1H NMR spectra must cover the range 10 ppm to – 1 ppm, or a suitable, wider range if signals are present outside these limits.
  • 13C{1H} NMR spectra must cover the range 200 ppm to – 10 ppm or a suitable, wider range if signals are present outside these limits.
  • 19F and 31P NMR spectra (and/or their decoupled equivalents) should be presented with a spectral width that includes all signals and has a window no smaller than 200 ppm.

Electrochemical nitrogen fixation checklist

If your manuscript reports electrochemical nitrogen fixation, a nitrogen fixation checklist will need to be completed and submitted alongside your manuscript prior to peer review. All manuscripts reporting on NH3 production must as a minimum include quantitative isotopic labelling experiments demonstrating that the amount of NH3 produced under 15N2 and 14N2 is equivalent. This checklist aims to improve the transparency of reporting and the reproducibility of published results on electrochemical nitrogen activation. Please refer to an Editorial article published in Nature Communications for further information.

Solar cells reporting checklist

If your manuscript reports photovoltaics research and you are notified that it will be sent to review at Communications Chemistry, you will be asked to complete the Nature Portfolio Solar cells checklist. Please see our editorial policies page for details and to download the Solar cells checklist document.

Gene nomenclature

Authors should use approved nomenclature for gene symbols, and use symbols rather than italicized full names (for example Ttn, not titin). Please consult the appropriate nomenclature databases for correct gene names and symbols. A useful resource is Entrez Gene, available from NCBI.

Approved human gene symbols are provided by HUGO Gene Nomenclature Committee (HGNC), e-mail: hgnc@genenames.org; see also www.genenames.org. Approved mouse symbols are provided by The Jackson Laboratory, e-mail: nomen@informatics.jax.org; see also www.informatics.jax.org/mgihome/nomen.

For proposed gene names that are not already approved, please submit the gene symbols to the appropriate nomenclature committees as soon as possible, as these must be deposited and approved before publication of an article.

Statistical guidelines

Comprehensive information on the statistical analyses used must be included in the paper. The Methods must include a statistics section with the following information. 

Every article that contains statistical testing should state the name of the statistical test, the n value for each statistical analysis, the comparisons of interest, a justification for the use of that test (including, for example, a discussion of the normality of the data when the test is appropriate only for normal data), the alpha level for all tests, whether the tests were one-tailed or two-tailed, and the actual P value for each test (not merely "significant" or "P < 0.05"). It should be clear what statistical test was used to generate every P value. Use of the word "significant" should always be accompanied by a P value; otherwise, use "substantial," "considerable," etc.

Data sets should be summarized with descriptive statistics, which should include the n value for each data set, a clearly labelled measure of centre (such as the mean or the median), and a clearly labelled measure of variability (such as standard deviation or range). Ranges are more appropriate than standard deviations or standard errors for small data sets. Graphs should include clearly labelled error bars. Authors must state whether a number that follows the ± sign is a standard error (s.e.m.) or a standard deviation (s.d.).

Authors must justify the use of a particular test and explain whether their data conform to the assumptions of the tests. Three errors are particularly common:

  • Multiple comparisons: When making multiple statistical comparisons on a single data set, authors should explain how they adjusted the alpha level to avoid an inflated Type I error rate, or they should select statistical tests appropriate for multiple groups (such as ANOVA rather than a series of t-tests).
  • Normal distribution: Many statistical tests require that the data be approximately normally distributed; when using these tests, authors should explain how they tested their data for normality. If the data do not meet the assumptions of the test, then a non-parametric alternative should be used instead.
  • Small sample size: When the sample size is small (less than about 10), authors should use tests appropriate to small samples or justify their use of large-sample tests.
