Abstract: The contribution of the quadrupole polarizability C to the long-range polarizability of two interacting rare-gas atoms and methane molecules is specified by fitting the trace and anisotropy models to the intensity of the isotropic and anisotropic interaction-induced light scattering spectra. Good agreement with ab initio results in the literature is obtained and the first few even moments of these profiles are in excellent agreement with experiments.
