A new method of evaluation of the structure of molten sodium chloride

Using the Waisman-Lebowtiz (WL) solution for the direct correlation functions (DCF), the partial structure functions (PSF) are computed by means of the Pearson-Rushbrooke relations for molten sodium chloride. The PSF's [Sij(K)] so computed are used to calculate the radial distribution functions (RDF) and hence the coordination numbers. In addition the number-number [SNN(K)], the charge–charge [SQQ(K)] and mass–mass [SMM(K)] correlation functions are also calculated. The long wave limit values of the PSF's are obtained and they are found to be in fair agreement with the experiment.
