Abstract
The Raman optical activity in the in-phase (A) methyl torsion fundamental of (2S,3S)-(-)2,3-epoxybutane is calculated using the general origin-invariant bond polarizability theory. The sign and magnitude are found to depend on the difference between the polarizability anisotropies of the ring carbon-methyl group and the ring carbon-hydrogen bond. The depolarized Raman circular intensity sum and difference spectra of (2S,3S)-(-)2,3-epoxybutane and (S)-(-)epoxypropane are presented, and a confident assignment of the in-phase methyl torsion fundamental in the former species allows a direct comparison between theory and experiment. Good agreement is found on the basis of available bond polarizability data.
