Coherent light scattering by interacting anisotropic molecules with variable dipolar polarizability

S. Kielich

A detailed theoretical analysis is given of cooperative light scattering, due to changes in polarizability of unlike molecules, anisotropic in their ground state. The changes in molecular polarizabilities considered are those induced by fluctuations of long-range electric dipolar fields in regions of near ordering. Complete calculations are performed with accuracy to the second order of changes in polarizability taking into account pure as well as cross contributions to the constants of isotropic and anisotropic light scattering. The contributions in question are related with two-body as well as three- and four-body interactions, on the specific assumption that the molecules are correlated radially but statistically independent orientationally.
