邻硝基乙酰苯胺衍生物电子结构的UPS研究

HeI Photoelectron Spectroscopic (UPS) Studies of the Electronic Structure on o - Nitro Acetanilide Derivatives

本文报道邻硝基乙酸苯胺衍生物的Hel紫外光电子能谱(PES),同时也给出了邻硝基苯胺衍生物的PES谱.PES谱的指认由相应分子的MNDO计算所支持,并指出带有不同取代基基团的邻硝基乙酰苯胺合成耐高温喹啉高聚物的难易依赖于PES所测化合物分子的最低电离能(IP).

HeI Photoelectron spectra of o - nitro acetanilide derivatives have been investigated systematically on a double - chambers UPS Machine - II which was especially designed for the study of transient species. The assignment of the spectra are also done using the optimized MNDO molecular orbital calculation for each molecules studied. It is shown that the difficulty of synthesis polymer from these o ~ nitro acetanilide derivatives depends on their lowest experimental ionization potential (IP ).
