Pseudo-spectral dipole oscillator strengths and dipole-dipole and triple-dipole dispersion energy coefficients for HF, HCl, HBr, He, Ne, Ar, Kr and Xe

Abstract

Pseudo-dipole oscillator strengths and excitation energies, which are discrete representations of original continuous dipole oscillator strength distributions (DOSDs), are tabulated for the ground state HF, HCl and HBr molecules and Ne, Ar, Kr and Xe atoms. These pseudo DOSDs are used to evaluate the dipole-dipole and triple-dipole dispersion energy constants for all possible two- and three-body interactions between HF, HCl, HBr, He, Ne, Ar, Kr and Xe. The importance of these results, and of the original DOSDs, is discussed briefly.
