2014采用同位素替代法,通过热中子衍射分别测量了熔融氯化钾和熔融氯化铯在800 °C和700 °C下的部分结构因子和三个径向分布函数。从部分结构因子限制在低动量转移,我们验证了经典的Orstein Zernicke关系的二元系统,我们推导出的数量级的纵向光学模式的频率。从偏分布函数的分析可以得出结论,这些离子液体的局部致密性相比于相应的固体有增加。一个最好的拟合与实验结果可以得到一个由硬球排斥相互作用的粒子系统的模型给出的相互作用势。LE JOURNAL DE PHYSIQUE托姆36,FÉVRIER 1975,
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.
