Abstract: This work proposes a comprehensive two‐dimensional gas chromatography method for the resolution and quantification of 27 amino acids, including 17 enantiomeric pairs, as stable N‐trifluoroacetyl‐O‐methyl ester derivatives. The derivatization approach in combination with enantioselective two‐dimensional… read more here.

DOI: 10.1103/physreva.100.033411
Abstract: 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 condition.… read more here.
