本文研究了硼氢化物BH-4离子在碱金属硼氢化物和钙硼氢化物中的离解模式。硼氢化钠的值以前已经从比热数据中推断出来，但这些盐的离解频率值以前没有直接确定。在硼氢化铯的情况下，它可以被冷却到液氮温度而不经历相变，在冷却时，Librational模式的频率增加，其宽度急剧下降。
This paper reports a study of the librational modes of the borohydride, BH–4, ion in the alkali metal borohydrides and in calcium borohydrides. Values for sodium borohydride have previously been inferred from specific heat data but values of the librational frequencies in these salts have not previously been determined directly. In the case of caesium borohydride, which can be cooled to liquid nitrogen temperatures without undergoing a phase transition, the frequency of the librational mode increases on cooling and its breadth decreases dramatically.
