Proposal for Chiral Detection by the AC Stark-Effect

Abstract

Recently, two related three wave mixing experiments have been demonstrated that use allowed rotational transitions to produce a free induction decay signal with an amplitude linearly proportional to the enantiomeric excess of a chiral molecule. In the present work, a formally five wave mixing experiment is proposed that will exploit near-resonant AC Stark shifts to differentially split a rotational transition of R and S versions of a molecule and thus will allow for the separate measurement of the densities of both enantiomers.
