Abstract
Raman circular intensity differentials observed in methyl asymmetric deformations and methyl torsions indicate that the methyl group could function as a powerful new probe of chirality. Torsional Raman optical activity could lead to new knowledge of barriers to internal rotation in molecules and aid the assignment of torsional modes.
