protonated with imidazole derivatives under neutral conditions and was absorbed at longer wavelengths compared with carboxylic acids. The absorption peak with the imidazolyl group intramolecularly combined was highly affected by the structure, protonated Nα-retinylidene-L-histidine octadecylamide having an absorption maximum at 494 nm caused by the inductive effect and the polar imidazolyl group.
