The electronic absorption spectra of furylmethylene and thienylmethylene derivatives of 2-aminopyridine, 2-aminopyrimidine and aminopyrazine have been investigated and INDO/S-CI molecular orbital calculations have been performed. The results predicted the position of n–π* transitions which were not observed experimentally. The coefficients of the CI wavefunction were used to predict the type of electronic transitions under consideration. It was confirmed that the anti conformer is the predominant one for the compounds studied.
研究了2-氨基吡啶、2-氨基嘧啶和氨基吡嗪的呋喃亚甲基和噻吩亚甲基衍生物的电子吸收光谱,并进行了INDO/S-CI分子轨道计算。结果预测了实验中未观察到的 n-π* 跃迁的位置。 CI 波函数的系数用于预测所考虑的电子跃迁类型。已证实反构象异构体是所研究化合物的主要构象异构体。
