本文对环丙基取代苯类系列化合物的光电子谱进行了分析和讨论,由于构象问题使得谱的解释变得复杂,但六环丙基苯(12)可能是个例外。现已证明在π-体系和环丙基之间无论是平分交叉构象,还是垂直构象都有明显的作用,其交叉项比值B(e_A,2p)/B(e_S,2p)≈1.4,不象传统的Walsh轨道所预料的那么大,文中阐述的由STO-3G模型导出的定域键轨道是一个更为合用、更具有启发性的模型。 In this paper, the photoelectron spectra of a series of cyclopropyl substituted benzenes are analyzed and discussed. The conformational problems complicate the interpretation of the spectra, but hexacyclopropylbenzene (12) may be the exception. It has been shown that there is a significant effect between the π-system and the cyclopropyl group on either the bifurcation or the vertical conformation. The ratio of the cross terms B (e_A, 2p) / B (e_S, 2p) ≈1.4 The traditional Walsh orbit expected so much that the localized bond orbit deduced by the STO-3G model set out in the paper is a more coherent and more enlightening model.
