Stark Field Modulated Microwave Detection of Molecular Chirality
Abstract
Patterson, Schnell, \& Doyle, Nature 497, 475 (2013) introduced a microwave experiment that produces a perpendicularly polarized molecular emission when chiral molecules are resonantly excited in the presence of a Stark Field that is then adiabatically switched off before observation of the emission. The sign of the signal is opposite for two stereo-enantiomers and thus the magnitude of the signal gives the enantiomeric excess of the sample. This paper presents a detailed presentation of the theory behind this and provides expressions for the absolute calculation of the expected signal strength for different transitions.
