Properties of H+ 2 relevant to the He—H+ 2 intermolecular potential: asymptotically increasing multipole moments, polarizabilities and dispersion coefficients.

Hutson, J. M.; Ernesti, A

Abstract

The quadrupole moment and polarizabilities of H+ 2 and the C 6 dispersion coefficients for He-H+ 2 are fitted to functional forms with the correct limiting behaviour for both large and small values of the H—H bond length r. Both the quadrupole moment and the dispersion coefficients increase quadratically with r at long range, while the polarizabilities increase exponentially. The reasons for the behaviour are analysed.
