4-trisisopropenylbenzene ( II ) was investigated by gas-phase UV photoelectron spectroscopy (UPS) and theoretical (HAM 3) calculations. In the case of compound I we found that the geometrical parameters do not effect appreciably the ordering and spacing of the highest occupied molecular orbitals whereas in II agreement between experimental and calculated IEs was found only for some geometries, characterized also by
摘要 通过气相紫外光电子能谱(UPS)和理论(HAM 3)计算研究了1,3,5-三异丙烯基苯(I)和1,2,4-三异丙烯基苯(II)的结构。在化合物 I 的情况下,我们发现几何参数不会显着影响最高占据分子轨道的排序和间距,而在 II 中,实验和计算 IE 之间的一致性仅在某些几何结构中发现,其特征还在于总能量最低。这种差异反映在两个分子的能级间距上。
