Abstract

CONFIGURATIONAL CHIRALITY BASED SEPARATION Abstract of the Invention Methods of determining the relative concentrations of enantiomeric forms of a compound in a racemic mixture can include combining the racemic mixture with carbon nanotubes or graphene to form a carbon-enantiomer mixture, exposing the mixture to a monochromatic polarized light, and analyzing reflected polarized light from the mixture using a differential analyzer.
