New Insights from an Empirical Multi-Property Interatomic Potential and Predicted Collision-induced Light Scattering Spectra for Hg-rare Gas van der Waals Complexes

Abstract

Abstract An empirical interatomic potentials for the interaction of Hg with inert gases are developed by simultaneously fitting the modified Tang–Toennies (MTT) potential function to spectroscopic data, thermo-physical and transport properties over a wide temperature range. The two-body anisotropic collision-induced light scattering spectra of mercury vapor with mixtures of rare gas has never been measured. The lineshape calculations through quantum mechanical methods have been used to predict a reasonable experimental spectra of the induced light scattering at T = 500 K using these models of potentials and a suitable models for the anisotropy. The results of calculations show that these models of the interactions and the induction mechanisms are the most accurate models reported to date for these mixtures.
