Site-averaging in the integral equation theory of interaction site models of macromolecular fluids: An exact approach
arXiv:cond-mat/0301514 · doi:10.1063/1.1560940
Abstract
A simple "trick" is proposed, which allows to perform exactly the site-averaging procedure required when developing integral equation theories of interaction site models of macromolecular fluids. It shows that no approximation is involved when the number of Ornstein-Zernike equations coupling the site-site correlation functions is reduced to one. Its potential practical interest for future theoretical developments is illustrated with a rederivation of the so-called molecular closures.
