Short-range order in molecular liquids : evidence from neutron diffraction data of carbon tetrachloride and deuterochloroform

Abstract
A ‘perturbed crystal’ model for short-range order provides quantitative agreement between observed and calculated neutron diffraction intensities from carbon tetrachloride and deuterochloroform. The nearest neighbour arrangement in CCl4 is based on a cubic close packed structure and lies close to a minimum in the calculated intermolecular potential energy.
