多原子有机自由基的光谱和化学动力学的研究,是深入了解认识化学反应规律和机制的重要环节。总的来说,我们关于这一类化学物种的认识还是初步的。这个方向上的研究工作是重要和迫切的。目前,多原子自由基的光谱和动力学的研究是分子光谱和化学动力学研究领域的一个前沿。本文主要回顾作者在这一方向上的初步的工作。 The study of the spectra and chemical kinetics of polyatomic organic free radicals is an important part of understanding the rules and mechanisms of chemical reactions. In general, our understanding of this group of chemical species is still preliminary. Research in this direction is important and urgent. At present, the study of spectra and kinetics of polyatomic free radicals is a frontier in the field of molecular spectroscopy and chemical kinetics. This article mainly reviews the author’s preliminary work in this direction.
