The electronic absorption spectra of three groups of furan derivatives: 2-formyl, 2-acetylfuran, and 2-furoic acid, N-(2-furylmethylene)amines and phenylfurans were investigated. The predominant conformation as well as the polarity of the molecule could be predicted from its spectrum. The investigated molecules were proved to be “all planar” configuration which led to substantial interaction between
研究了三组呋喃衍生物的电子吸收光谱:2-甲酰基、2-乙酰基呋喃和 2-呋喃酸、N-(2-呋喃亚甲基) 胺和苯基呋喃。可以从其光谱预测分子的主要构象和极性。研究的分子被证明是“全平面”构型,这导致了子系统的电子状态之间的大量相互作用。借助分子轨道计算预测了 N-(2-呋喃亚甲基) 甲胺和 N-(2-呋喃亚甲基) 苯胺的优选构象。
