通过中子一阶差分方法研究了不完全水合溶液中Li+周围的水合性质（Soper等人，1977），使用飞行时间中子衍射仪。作者首次观察到Li-Cl相关性的直接证据，这反映了水分子与Li+之间以及Cl-与Li+之间在大约4 AA内的短程相关性。Li-O轴和水分子平面之间的角度和水合数强烈地依赖于浓度，甚至对于大于约25摩尔%的不完全水合溶液也是如此。氯化锂
The nature of hydration around Li+ in incompletely hydrated solution was investigated by the neutron first-order difference method (Soper et al., 1977), using a time-of-flight neutron diffractometer. The authors observed, for the first time, direct evidence of Li-Cl correlations, which reflect the short-range correlations between water molecules and Li+ as well as between Cl- and Li+ within approximately 4 AA. The angle between the Li-O axis and the plane of the water molecule and the hydration number were strongly concentration dependent, even for incompletely hydrated solutions at large than approximately 25 mol.% LiCl.
