2014 The partial structure factors and the three radial distribution functions of molten potassium chloride and molten cesium chloride were measured respectively at 800 °C and 700 °C by the diffraction of thermal neutrons using an isotopic substitution method. From the partial structure factor limits at low momentum transfers we verify the classical Orstein Zernicke relation for binary systems and we deduce an order of the magnitude for the frequency of the longitudinal optical mode. From the analysis of the partial distribution functions it can be concluded that there is an increase in the local compacity of these ionic liquids compared to the corresponding solid. A best fit with the experimental results could be obtained for an interaction potential given by the model of a system of particles with hard-sphere repulsive interactions.
