Generalization to ion—neutral systems of the polarizability correlations for interaction potential parameters

Abstract Correlations in terms of particle polarizabilities are developed for both positive and negative ion—neutral interactions extending a general scheme previously proposed. For a proper assessment of the parameters, the ratio of the dispersion to the induction energy is evaluated in terms of the polarizability of the interacting partners. The correlations are successfully tested for a variety of ion—neutral systems. Their use to predict the potential parameters of unknown systems is suggested.
