| Abstract: | The depolarized light scattering intensity and second Kerr virial coefficient for SF6 are two to three times the values calculated with the dipole-induced-dipole model for the pair polarizability anisotropy and a Lennard-Jones pair potential. Contrary to earlier suggestions, this discrepancy is not attributable to the distribution of polarizable matter within an SF6 molecule, at least within the point-atom-polarizability approximation. However, the calculated thermal average of the square of the polarizability anisotropy for SF6 can be doubled by replacing the Lennard-Jones potential with a modified Lennard-Jones potential. |
