Job description:

Reference No. FG 2018/14The Department Highly sensitive X-ray spectroscopyis looking for 2 PhD students (m/f) (MSc in Physics or Chemistry) in cryogenic gas-phase XAS and XMCD studies of organometallic compounds, transition metal clusters, and complex ions What we offer:Applications are invited for two PhD positions at the Department of Highly-Sensitive X-ray Spectroscopy. The main objective is to investigate the role of ligands in determining spin states, electronic configuration, and bonding of the metal centers in gas-phase coordination entities and clusters. The species of interest are generated by a range of methods including magnetron sputtering, gas-phase ion chemistry, and electrospray ionization. Mass-selected samples are mainly probed in a cryogenic ion trap but a liquid jet set-up is also available for complementing studies of samples in solution. The candidate will work closely with a team of postdoctoral research associates and PhD students and will have a choice between the following PhD projects:

Small transition metal-oxide clusters and their interaction with water ligands: oxidation states, spin states, geometry, and reactivity Stepwise coordination of transition metal ions by carbonyl ligands: from coordinatively unsaturated to coordinatively saturated 17, 18, and 19 electron species Transition metal chelate ions and organometallic coordination entities in gas-phase and solution: the influence of ligands and solvation on the metal centerMagnetic moments and magnetic anisotropy energy of gas-phase single-ion magnets What we are looking for:We are seeking for two highly motivated PhD students with a strong interest in experimental x-ray spectroscopy of gas-phase or liquid-phase atomic, molecular, and cluster ions. To qualify for this position, the candidates should hold or have

a recent MSc degree in physics, chemistry, or a related fieldexpertise with x-ray absorption spectroscopy, x-ray magnetic circular dichroism spectroscopy, or resonant inelastic x-ray scattering at synchrotron radiation sources or free-electron lasersexperience with one or more of the following: ion beams, liquid jets, time-of-flight mass spectrometry, RF multipole ion guides, RF ion traps, metal ion sources, electrospray ionization, organometallic chemistry, gas-phase ion chemistry, cryogenics, high vacuumthe ability and willingness to perform cutting-edge research in international teams and to participate in beam times, which also includes occasional night or weekend working hours Further Information Prof. Dr. Tobias Lau+49 30 8062 14786tobias.lau@helmholtz-berlin.de Closing Date: 15.12.2018 apply
