How well do we know the structure of simple molecular liquids? CCl₄ revisited

Abstract

New experimental results for the full intermolecular pair correlation function for liquid carbon tetrachloride have been obtained from analysis of structure factors measured using reactor and pulsed neutron sources. A brief comparison between the results derived from both techniques is presented. The liquid structure is discussed within the framework of the site-site Ornstein-Zernike equation with the hypernetted chain (HNC) and Percus-Yevick (PY) like closures. The Coulomb potentials are handled using Ng's method. The predictions show that the octupolar interactions have a small effect on the radial distribution functions.
