摘要
测定了23种芳香胺样品的红外光谱,对氨基伸缩振动吸收峰与其结构的关系进行了探讨。结果发现,在固体和纯液体状态下,大部分芳香胺都有较强的氢键缔合,取代基的性质对氨基氢键的形成有较大的影响。在非极性溶剂中难以形成分子内氢键的分子,在此状态下有较强的分子内氢键。
The IR spectra of 23 aromatic amines were determined and the relationships between the spectra of amide group s stretching vibrational absorption and their structures have been investigated. The results show that most of aromatic amines have strong inter-and intra-molecular hydrogen bonds in solid or pure liquid states. The properties of substituents have tremendous influence on the hydrogen bond formation of amide groups. There are strong intra-molecular hydrogen bonds for those molecules that are difficult to form hydrogen bond in non-polar solvents.
