The binary isotropic collision-induced scattering spectra of the gaseous tetrauoromethane has been measured in absolute units in the 50–150 cm-1 frequency range. Corresponding theoretical intensities taking into account multipolar polarizabilities have been calculated in a semiclassical way. From a comparison with experiment, the independent components of dipole-quadrupole and dipole-octupole polarizability tensors have been estimated. They have been compared with those previously deduced from depolarized spectrum and with recent theoretical ab initio calculations
