月桂胺盐酸盐晶体的红外光谱研究表明,标题化合物两个结构相变的起始温度分别为327和339K。在327K以下晶体中分子以TT构象存在并以分子链相互平行的叉指状形式填充,339K以上分子以TG构象和部分GTG’构象存在并以非叉指状的六方形式填充,在327～339K之间则是一个分子构象由有序到无序、链填充由叉指状到非叉指状转变的中间过渡相。
Infrared spectra of lanthanamine hydrochloride crystals showed that the onset temperatures of the two structures of the title compounds were 327 and 339 K, respectively. In the crystals below 327K, the molecules exist as TT conformers and are filled in the interdigitated interdigitated interdigitated fingers. The 339K or more molecules are in the TG conformation and part of the GTG ’conformations and are filled in hexagonal form with non-interdigitated fingers. At 327 ~ 339K Is a molecular conformation from order to disorder, the chain filled by the interdigital transition to the interphase transition phase.
