Polarized and depolarized collision-induced light scattering spectra of xenon gas at room temperature 295 K with the pressure second virial coefficients, viscosity and thermal conductivity have been used for deriving the empirical models of the pair-polarizability trace and anisotropy and the interaction potential. Theoretical zeroth and second moments of the binary spectra using various models for the pair polarizabilities and interatomic potential are compared with the experimental values performed by Frommhold’s group. In addition, vibrational energy levels, self diffusion coefficients and second virial dielectric constants calculated for these models are compared with experimental ones. The results show that these models are the most accurate models reported to date for this system.

The higher order dipole–octopole polarizability E of sulfur hexafluoride has been determined from isotropic and anisotropic collision-induced light scattering (CILS) experiments of pure SF6 gas and from anisotropic light scattering of its mixture with inert gases. The CILS spectra are analyzed by using the new updated and different intermolecular potentials. Our final estimates for this property is |E| = 96.405 ± 12.045 a.u. which is in excellent agreement with the ab initio theoretical value.
