N2 - The theory of differential scattering described in part I (preceding paper) is applied to the Raman process. Here, a distinction between inequivalent and equivalent chromophores is required. For systems with inequivalent chromophores, the leading contribution to the differential intensity of scattering involves the interference of second- and fourth-order probability amplitudes; in near- and far-zone limits, it depends on the inverse square of the group separation. For systems with equivalent chromophores, the spectrum should, in general, feature a doublet. The dominant contribution to the differential intensity comes from the second-order-second-order interference term and has a different sign for each doublet component. In many cases these contributions cancel and the leading term becomes the second-order-fourth-order interference term as in the case of inequivalent chromophores.
