Observation of Rayleigh optical activity for chiral molecules: a new chiroptical tool

By measuring a small circularly polarized component in the scattered light, we report the first observation of Rayleigh optical activity (RayOA) for isotropic samples of chiral molecules, namely the two enantiomers of $α$-pinene in neat liquid form. Our work validates fundamental theoretical predictions made over fifty years ago and expands the chiroptical toolkit.

Theory of Rayleigh-Brillouin optical activity light scattering applicable to chiral liquids

It has long been understood that dilute samples of chiral molecules such as rarefied gases should exhibit Rayleigh optical activity. We extend the existing theory by accounting for molecular dynamics and correlations, thus obtaining a more general theory of Rayleigh-Brillouin optical activity applicable to dense samples such as neat liquids.
