An analysis of regularities m the van der Waals forces has been performed for over fifty systems. Correlauons are found betueen features of the interactIon. namely the well depth and tts IwzatIon, and atomic propertles such as the polartzabihty. These correlanons can be extended to the spherical par
In continuation of earlier work. an atomistic derivation is given of Lifshitz' formula for the non-retarded Van der Waals interaction between two semi-infinite dieIectric media. In the derivation an atom is supposed to consist of a number of isotropic harmonic oscillators.
New combining rules are proposed for the well depth, E , and interaction distance, a, describing nonbonded interatomic forces for rare gas pair interactions. Concepts underlying current combining rules applied in simulations of macromolecular and polymer systems are shown to be incompatible with exp
