Abstract

Circular dichroism (CD) in the vibrational transitions of three different series of molecules-namely, phenylcarbinols, carboxylic acids, and oxiranes-containing the benzene group is measured. It is found that a benzene-group vibration, where the hydrogen atoms in the meta and para positions vibrate in a concerted semicircular path, gives rise to CD that is consistent with the molecular stereochemistry. This observation provides a practical approach to the use of the benzene group as a probe of molecular chirality.
