# Publisher Correction: Massively parallel sensing of trace molecules and their isotopologues with broadband subharmonic mid-infrared frequency combs

### Subjects

Correction to: Nature Photonics https://doi.org/10.1038/s41566-018-0135-2, published online 26 March 2018.

In the version of this Article originally published, in equation (9), the ‘Δ’ in the first 'Δfrep' shouldn’t have been included; the equation should have read

$${\nu }_{m}=({{\rm{\nu }}}_{1m+1}+{{\rm{\nu }}}_{2m})/2={{\rm{\Delta }}}_{1}/2+\left({{m}}+\frac{1}{2}\right){f}_{{\rm{rep}}}-\frac{\Delta {f}_{{\rm{rep}}}}{4}$$
(9)

And, in equation (10), within the brackets, frep and f were the wrong way round; the equation should have read

$$\nu ={{\rm{\Delta }}}_{1}/2+\frac{{f}_{{\rm{rep}}}}{{\rm{\Delta }}{f}_{{\rm{rep}}}}({f}_{{\rm{rep}}}-f)-\frac{\Delta {f}_{{\rm{rep}}}}{4}$$
(10)

These equations have now been corrected in the online versions.
