## Abstract Empirical force field calculations were performed on hexamethylbenzene to elucidate the internal motions of the methyl groups. When the benzene ring is constrained to be planar (as in solidβphase studies), the methyl groups undergo a geared, disrotatory motion. When this constraint is r
