Abstract:
Using the Ni surface-catalyzed excitation method, we obtained the (0,0) electronic transition spectra of atmospheric oxygen band (b1Σg+→X3Σg-) from the recombination of ground state oxygen atoms O(3P) in flowing afterglow apparatus. We experimentally analysed the kinetic process of deactivation of O2(b) by the wall, which indirectly proved that the concentration of O2(b)changed in a nonsteady-state way in the flowing tube. Meanwhile, the formation mechanism of O2 (b) was simply discussed.

摘要:
利用流动余辉装置,首次报道了金属镍表面催化基态氧原子O(3P)复合从而获得大气氧谱带O2(b1Σg+→X3Σg-)的(0,0)电子跃迁光谱。并且对反应管壁去激活O2(b1Σg+)的动力学过程进行了分析,间接证实了O2(b1Σg+)的浓度在反应管中是非稳态的变化过程。最后对O2(b1Σg+)的形成机理进行了简单的讨论。
