Abstract
The X-ray scattering function for liquid carbon disulphide at 20°C has been measured. We interpret these data using a Fourier inversion procedure, and by using two statistical mechanical models for the pair-correlation function for this linear molecule. Only one of these methods, that using the reference-site-interaction model (RISM), is in good agreement with our data. Using RISM fitted to our experimental data, estimates are made for the intermolecular carbon-carbon, carbon-sulphur and sulphur-sulphur correlation functions, for the like and unlike atomic coordination numbers, and for the correlation functions for several fixed orientations.
