Molecular Theory of Liquids and Liquid Mixtures

This paper reviews the present position of statistical or molecular theory of simple liquids and their mixtures, with particular emphasis on the quantitative success of perturbation theories. It is shown that the limits to our present understanding are provided not so much by imperfections in the statistical mechanics as by our ignorance of the precise form and strength of the intermolecular potentials for all molecules except the noble gases and their mixtures.
