Neutron diffraction study of liquid carbondiselenide

Abstract

A study of an orientational model approach for molecular liquid CSe₂ is given. With proper selection of the centres structure factor and weighting of parallel and perpendicular orientations, an agreement comparable with the reference interaction site model (RISM) calculations can be obtained, except in the low Q region. Next, from the experimental molecular structure factor data calculations are made for the centres structure factor, centres radial distribution, centres direct correlation, intermolecular potential energy and, finally, the partial structure factor of Se in CSe₂.
