โฆ Synopsis
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 quadrupole polarizability components and moments of inertia at equilibrium geometry.
