摘要
He (23S)， He'和He2+与S02, SOC12, SOBr2, S02C12和S02FCI反应产生的发射光谱在氦气流动的余辉中进行了测量，以研究导致SO' (A2IIi)的解离电离过程。He'与so02、SOC12和S02C12反应中存在SO+ (A2Hi' x2hr)发射体系，但He'与SOBr2和S02FCI反应中没有。三种反应的SO′(A)的振动分布随v′的增大而呈指数型减小。so02、SOC12和so02c12的有效振动温度分别为3320A}230、4620A}760和3100A}300 K。
Vibrational Distributions od SO^+(A^2Π_i) Produced from Dissociative Ionization of SO-Containing Molecules in a Helium Flowing Afterglow
Emission spectra resulting from the reactions of He (23S) , He', and He2+ with S02, SOC12, SOBr2, S02C12, and S02FCI have been measured in a helium flowing afterglow in order to examine dissociative-ionization processes leading to SO' (A2IIi) . Although the SO+ (A2Hi'X2Hr) emission system was observed from the reactions of He' with S02, SOC12, and S02C12, it was absent from those of He' with SOBr2 and S02FCI. The vibrational distributions of SO" (A) decreased nearly exponentially with increasing v' for all the three reactions. The effective vibrational temperatures of SO'(A) were determined to be 3320A}230, 4620A}760, and 3100A}300 K for S02, SOC12, and S02C12, respectively.
