摘要 在 28 至 5O°C 之间测量了 8CB 的密度,并确定了 SA-N 和 N-I 转变时的体积变化。 SA-N 似乎是一阶。讨论了关于氰基联苯不寻常结构中的分子堆积的结果的含义,其中层间距约为分子长度的 1.4 倍。
Abstract The density of 8CB has been measured between 28 and 5O°C and the volume change at the SA-N and N-I transitions determined. The SA-N appears to be first order. The implications of the results are discussed with respect to the molecular packing in the unusual structure of the cyanobiphenyls in which the layer spacing is about 1.4 times the molecular length.
