研究亚稳态分子与小分子、自由基的传能反应是近年来比较活跃的课题,它主要是利用N_2(A~3∑_u~+,6.12eV)和CO(α~3Ⅱ,6.02.eV)作为共振传能的能量载体,已经观察到N_2(A)、CO(α)与OH,NO,CS,SO,S_2等能量转移过程。 CN自由基作为一种红外激光介质,已得到了广泛的研究。为了实现其近紫外辐射跃迁CN(B-X),可以用光解、电子轰击或亚稳态惰性气体原子与含烃化合物碰撞传能,获得CN(B~2∑~+)的激发态碎片,而利用亚稳态CO(α)分子与CN(X)进行能量转移反应得到CN(B)则是本文首次报导。
Studying metastable molecules and small molecules, the energy transfer reaction of free radicals is a relatively active subject in recent years. It mainly utilizes N 2 (A ~ 3Σ_u ~ +, 6.12eV) and CO (α ~ 3Ⅱ, 6.02.eV As energy carriers for the resonant energy transfer, the energy transfer processes of N 2 (A), CO (α) and OH, NO, CS, SO, S 2 have been observed. CN free radical as an infrared laser medium, has been widely studied. In order to achieve its near-UV radiation transition CN (BX), excited-state fragments of CN (B ~ 2Σ ~ +) can be obtained by collisional transfer of photon, electron bombardment or metastable inert gas atoms with hydrocarbon-containing compounds CN (B) was obtained by energy transfer reaction between metastable CO (α) molecule and CN (X), which is the first report in this paper.
