A simple variation method is employed to obtain an expression for the dispersion interaction of closed-shell atoms in term of sum rule properties of the dynamic multipole polarizabilities of the interacting atoms. An analytical es&e&on for the dispersion cocfficicnts for the interaction of hydrogen
The relation between the variation-perturbation method and sum rule methods is explored. Thevariation-perturbation method is a simple method which yields accurate numerical results for all higher-order multipole dispersion coefficients. T&is method is related to a method which obtains bounds on dis

The electron gas model of Gordcn and Kim is applied to the interaction of inert gases with a hydrogen molecule. Comparison of the isotropic potential wells with available experimental data shows clearly that modification of the exchange potential along the lines suggested by Rae produces greatly imp
