ISOTROPIC COLLISION-INDUCED LIGHT-SCATTERING BY GASEOUS CF4

The binary isotropic collision-induced scattering spectra of the gaseo us tetrafluoromethane has been measured in absolute units in the 50-15 0 cm(-1) frequency range. Corresponding theoretical intensities taking into account multipolar polarizabilities have been calculated in a se miclassical way. From a comparison with experiment, the independent co mponents of dipole-quadrupole and dipole-octupole polarizability tenso rs have been estimated. They have been compared with those previously deduced from depolarized spectrum and with recent theoretical ab initi o calculations.
