Multipolar polarizabilities isotropic scattering

The influence of multipolar polarizabilities has been examined subsequently in several optically isotropic molecules such as CH4, CD4, neopentane, CF4, or SF6 [4,7-14,17,18]. In this review, our attention is focused on CF4 for which both Rayleigh [8,13] and Vi Raman [17,18] depolarized and isotropic bands have been studied and published by us. In the Rayleigh studies, we measured the /j (v) and / (v) intensities that are scattered by gaseous CF4 up to 340 cm-1, in... 

In summary, since the early 1980s or so, collision-induced light scattering experiments on molecular fluids have demonstrated that the study of the collision-induced absolute-unit spectra (depolarized and/or isotropic ones) is an useful tool, and up to now the only one, to measure multipolar polarizabilities of molecules.
