Depolarized collision-induced light-scattering spectra of CCl4 in the saturated vapour-phase have been measured in the ranges of temperature and density between T = 501 and 561 K and Q = 687 and 1524 Mol m(-3), respectively. The CILS spectra are analyzed by using an isotropic Lennard-Jones type (18.6-6) intermolecular-interaction potential. It is found that the polarizability anisotropy of the CCl4-dimer contains a significant short-range repulsive term. Taking into account collision-induced rotational Raman scattering (CIRR) the dipole-quadrupole polarizability A, and dipole-octopole polarizability E Of CCl4 were obtained as \A\ = 3.8(1.0) x 10(-40) m(4) and \E\ < 4 x 10(-49) m(5).
