The expressions for the sum of vibrational Raman optical activity (ROA) intensities indtcate that the ROA intensity sum for chiral molecules is non-zero for those with an anisotropic electric dipole polarizability. The non-zero sum depends upon the electric dipole, magnetic dipole and electric quad

We prove that the lowest order contributions to the high frequency optical activity of any system is non-zero only if there are two or more electrons in the system.
Vibrational Raman optical activity (R.o.a.) spectra of a range of carbohydrates in aqueous solution, measured in back-scattering between 700 and 1500 cm-1, are presented. Features were revealed that appear to be characteristic of details of the stereochemistry. Effects associated with the glycosidic
