Abstract
The Kirkwood-Yvon dielectric theory is generalized to the case of fluids consisting of molecules possessing arbitrary polarizability densities. The theory is used to find expressions for the equilibrium dielectric constant, the polarized scattering intensity, and the depolarized scattering intensity, which we have previously calculated under the approximation (PPA) that molecules have point polarizabilities. A simplified version of the general theory, in which each atom in a polyatomic is given a point polarizability (PAPA), is proposed, and worked out in detail for the case of homonuclear diatomics. A discussion is given of how we hope to obtain numerical results in the near future for liquids composed of model homonuclear diatomics considered by us previously.
