IS DEPOLARIZED LIGHT SCATTERED FROM SIMPLE LIQUIDS MAINLY DOUBLE-SCATTERED

The multiple-scattering series for depolarized light scattering from simple liquids is investigated. It is found that the leading term in the series, due to double-double scattering, is probably not large compared to double-triple (DT) scattering contributions. Existing theories, which neglect DT scattering, have concluded that the experimental data cannot be explained using the dipole-induced dipole (DID) model for the pair polarizability. It is suggested that a theory which includes DT scattering will not lead to rejection of the DID model. © 1979.
