ON THE THEORY OF THE REFRACTIVE INDEX OF NON-POLAR GASES. I. QUANTUM MECHANICAL PART,
Abstract
A quantum mechanical calculation is given for the effect of molecular interactions on the polarizability of spherical non polar molecules in a periodic external electric field. The polarizability tensor is obtained from perturbation theory as a power series in the interaction tensor. It is found that the constants C sub 1 and C sub 2 introduced by Jansen and Mazur in the static case, and characterizing the influence of molecular interactions on the polarizability, become now frequency dependent. This frequency dependence is explicitly evaluated for helium at frequencies of the incident wave small compared to the frequencies of the softest absorption line. (Author)
