Molecular Correlation Functions in Liquid Carbon Disulfide and Carbon Diselenide

Abstract

Neutron diffraction structure factors for liquid carbon disulfide and liquid carbon diselenide have been measured and are analyzed to determine molecular correlation functions using the methods developed by Egelstaff, Page, and Powles. This analysis shows that the parallel molecular configuration is more probable in CSe2 than the T configuration expected from molecular quadrupole interactions. In CS2 the data are related to the carbon–carbon correlation function, which is shown to be similar to that for monatomic liquids.
