of substituted furans as determined by photoelectron spectroscopy are compared with the results of CNDO/2calculations. The analysis of the photoelectron spectra and quantum chemical calculations for furylsilanes, difurylsilanes and some carbon analogs has shown the importance of the pπ-dπ interaction as well as of the conjugation and necessity of the inclusion of silicon d-atomic orbitals into the
将通过光电子能谱确定的取代呋喃的第一个垂直π电离能与CNDO / 2计算的结果进行比较。光电子光谱和量子化学计算为furylsilanes,difurylsilanes和一些碳类似物的分析已经显示出的重要性p π - d π相互作用以及缀合并且包含硅的的必要性的d -原子轨道到基本放。
