Abstract

A general discussion is given about the depolarization ratio of the collision-induced light scattering. In the high density range, experimental results obtained for depolarized Rayleigh and vibrational Raman scattering, in the case of atomic and isotropic molecular fluids, are compared to theoretical results calculated in the framework of the classical DID theory by using the lattice gas model or molecular dynamics simulations. At low densities, a comparison is made between data obtained either from the depolarization ratios, or from spectral line shapes, in the case of argon and methane; experimental results are also compared to DID values. It is found that there are some discrepancies which are discussed.
