Abstract
The two-body isotropic and anisotropic collision-induced light scattering spectra of mercury vapour at different temperatures are analysed in terms of new interatomic potential and interaction-induced pair-polarisability trace and anisotropy models, using quantum line-shape computations. The quality of the present potential has been checked by comparing between calculated and experimental spectroscopic, thermo-physical and transport properties over a wide temperature range, which are found to be in good agreement. Also, the comparison of the computed spectra with a measurement at different temperatures permits improvements on the existing trace and anisotropy models of the pair polarisability.
