激发态分子和自由基的反应是大气化学、化学激光、燃烧化学中重要的过程,有关亚稳态分子的传能反应一直受到人们的极大重视.Setser在流动体系中,对CO(a)与NO分子的反应进行了初步研究,求得了产物的形成速率,Ottinger在束气条件下,利用CO~+束源与NO作用,认为CO~+与NO首先发生共振激发传能产生CO(a)再进一步与NO反应,但事实上他并没有观察到CO(a)的发射.本工作在分子束条件下,利用束放电方法产生高浓度的亚稳态CO(a)分子束并与NO反应,得到了振转分辨的NO(A)化学发光光谱,并结合相空间理论进行了讨论.
The reaction between excited state molecules and free radicals is an important process in atmospheric chemistry, chemical laser and combustion chemistry, and the transfer reaction of metastable molecules has been paid great attention to by people.In the flow system, The reaction of NO ~ + with NO was studied. The formation rate of the product was obtained. Under the condition of the beam gas, Ottinger used the CO + ) And further reacted with NO, but in fact he did not observe the emission of CO (a) .This work uses a beam discharge method to generate a high concentration of metastable CO (a) Reaction, get the vibration-resolved NO (A) chemiluminescence spectrum, and the phase space theory is discussed.
