Abstract
A representation of the long-range dispersion series proposed by Smith and Thakkar (1972) and rediscovered by LeRoy (1974) requires a choice of n or equivalently chi =C10C6/(C8)2. chi is nearly constant for interactions between pairs of S-state atoms. This constancy is explained in terms of the single oscillator model, the hydrogenic model and the Starkschall-Gordon model.Keywords
