Bipolar Electrochemical Measurement of Enantiomeric Excess with Inherently Chiral Polymer Actuators. [PDF]
ACS Meas Sci Au, 2021 Straightforward enantioselective analytical methods are very important for drug safety, considering that in certain cases one of the two enantiomers of a chiral molecule might be harmful for humans. In this work, we propose a simple system for the direct

Determination of enantiomeric excess with chirality-dependent ac Stark effects in cyclic three-level models [PDF]
Physical Review A, 2019 Determination of enantiomeric excess is important and remains challenges. We theoretically propose a new spectroscopic method for this issue based on the chirality-dependent AC Stark effects in cyclic three-level models under the three-photon resonance ...

Enantiomeric excess by magnetic circular dichroism in Archaean atmosphere. [PDF]
Sci Rep, 2017 AbstractEvolution of homochirality requires an initial enantiomeric excess (EE) between right and left-handed biomolecules. We show that magnetic circular dichroism (MCD) of sun’s ultraviolet C light by oxygen in Archaean earth’s anoxic atmosphere followed by chirally selective damage of biomolecules due to circular dichroism (CD) can generate EE of ...
