Abstract
Dipole oscillator strength distributions (DOSDs) have been constructed for ground SF6 including the IR, UV, and higher energy parts of the absorption spectrum. An adopted DOSD is used to evaluate the dipole oscillator strength sums Sk, k=2,1, 1/2 (− 1/2 )−3,−4,−6,..., mean excitation energies Ik, k=2(−1)−2, dipole–dipole dispersion energies for the interaction of SF6 with itself and with Li, N, O, H2, N2, O2, NO, H2O, NH3, CO2, CO, H, He, Ne Ar, Kr, and Xe, and the triple–dipole dispersion energy for (SF6)3. Pseudo‐DOSDs have been constructed for SF6 which facilitate the evaluation of the dispersion energies involving SF6. In most cases uncertainties in our results for the dipole properties and dispersion energy coefficients are ≲1–3%.
