Raman optical activity of menthol and related molecules

Abstract

Raman circular intensity difference spectra between 80 and 2 000 cm^–1 of (–)-menthol, (–)-menthylamine, (–)-menthyl chloride, (–)-isopulegol, (–)-menthone, (–)-3,3-dimethylcyclohexanol, (+)-pulegone, (–)-limonene, and (+)-carvone are presented. Several stereochemical correlations are pointed out involving, in particular, bands characteristic of the isopropyl and gem-dimethyl groups, methyl torsions, and out-of-plane olefinic hydrogen deformations.
