TL;DR: In this paper, general correlations between van der Waals interaction potential parameters and polarizabilities of the interacting neutral-neutral partners of any nature are presented and discussed, and an evaluation of the long-range interaction constants is performed in terms of the Slater-Kirkwood approximation whose numerical coefficients, having the meaning of effective electron numbers, are estimated interpolating the values deduced by theoretical considerations.

TL;DR: In this paper, a new method is proposed to calculate bond energies and equilibrium distances in atom-molecule van der Waals complexes which arises from a balancing between long-range attraction and asymptotic tail of the repulsion.

TL;DR: In this paper, the relationship between particle polarizabilities and particle dispersion was developed for both positive and negative ion-neutral interactions extending a general scheme previously proposed, and the correlations were successfully tested for a variety of ionneutral systems and their use to predict the potential parameters of unknown systems is suggested.

TL;DR: In this article, the interaction energy in systems (atom-atom, atom-ion and atom-molecule) involving open-shell species, predicted by a phenomenological method, is used for collision integral calculations.

TL;DR: In this paper, an analysis of regularities in the van der Waals forces has been performed for over fifty systems and correlations are found between features of the interaction, namely the well depth and its location, and atomic properties such as the polarizability.
