depolarized light scattering by CF 4

Abstract

Tetrafluoromethane gas depolarized scattering has been recorded at 294·5 K and 20·3 amagat in the frequency range 2-340 cm⁻¹. Two-body depolarized scattered intensities have been measured in absolute units up to 150 cm⁻¹. The theoretical intensities taking into account multipolar polarizabilities and several hyperpolarizability contributions have been calculated. From comparison with experiment, the independent components of the dipole-quadrupole and the dipole-octopole polarizability tensors have been estimated and checked with recent ab initio theoretical values.
