讨论了溶剂和介质对各个染料紫外可见吸收光谱及偶氮式异构体与腙式异构体互变平衡的影响。

Hydrocyanic acid and water proceed via a five-centred transition states then transformed by its exterior hydrogen-bond; The results show that the activation energy of the isomerizing reaction in the aqueous phase is lower than that in the gas phase. It is likely that the hydrogen bonds formed in the complexes and the solvent effect play an important role.

计算结果表明，在水相中异构化过程的活化能比在气相中低，无论在气相还是在水相中异氢氰酸通过水氢键转化成氢氰酸容易些，而氢氰酸由水氢键转化成异氢氰酸相对要困难些，分子间氢键和溶剂化效应在异构化反应过程中起到重要的作用。
