phase is discussed. HeI photoelectron and mid-infrared spectroscopy are used, for the first time, to obtain spectra of the oxime and furoxan precursors, and of the thermolysis products, the substituted nitrile oxides. Assessment of the structures for these three apparently disparate groups of compounds is assisted by conventional ab initio calculations, and also by calculations employing density functional
摘要 讨论了二卤代甲醛肟和二取代呋喃烷在气相中作为瞬态氧化腈发生剂之间的关系。HeI 光电子和中红外光谱首次用于获得肟和呋喃前体的光谱,以及热解产物取代的腈氧化物的光谱。这三个明显不同的化合物组的结构评估通过常规的从头计算以及使用密度泛函理论的计算来辅助。
