  Evanescent-wave and ambient chiral sensing by signal-reversing cavity ringdown polarimetry

  By passing light through a chiral sample — here vapours and solutions — in a specially designed ring cavity, the resulting chiral signals can be isolated from the achiral backgrounds and enhanced by a factor of more than 1,000, making them detectable in situations where conventional means of measurement fail.

  Enantiomer-specific detection of chiral molecules via microwave spectroscopy

  Microwave spectroscopy is used to map the sign of an electric dipole Rabi frequency — which depends directly on the chirality of the molecule — onto the phase of emitted microwave radiation, thereby determining the chirality of cold gas-phase molecules.
