亚稳态SO(c1Σ－,v’=0)的猝灭动力学
摘要:
在流动余辉装置上, 研究了SO(c1Σ－)的猝灭动力学过程. 获得了SO2, O2, CO2, N2, He, CS2, CH3OH, C2H5OH, C3H7OH, C4H9OH, CH3COCH3, C6H6, CH2Cl2, CH2Br2, CHCl3, CCl4等16种分子与SO(c1Σ－)发生猝灭反应的速率常数. 初步分析表明: 醇类分子CnH2n+1OH(n=1, 2, 3, 4)中的C—H键的数目与其对SO(c1Σ－)的猝灭速率成正比; CO2, N2等非极性无机小分子对SO(c1Σ－)的猝灭作用不明显, 强极性分子SO2对SO(c1Σ－)的猝灭作用较强. 卤代烷烃中的卤素原子的大小对SO(c1Σ－)的猝灭过程发挥着较重要的作用; 而氯代烷烃中氯原子的个数与猝灭速率之间的关系不明显.

Studies on the Quenching of SO (c1Σ－,v’=0)
Abstract:
On a flowing afterglow apparatus, the quenching of SO(c1Σ－) by SO2, O2, CO2, N2, He, CS2, CH3OH, C2H5OH, C3H7OH, C4H9OH, CH3COCH3, C6H6, CH2Cl2, CH2Br2, CHCl3, or CCl4 was studied firstly and successfully. The quenching rate constants of SO(c1Σ－) by them were measured. By analysis, it demonstrates that the quenching rate constants of SO(c1Σ－) by the alkanol molecules, CnH2n+1OH(n=1, 2, 3, 4), are semi-proportional to the number of C—H bond in them; the quenching by the non-polar small molecules, such as CO2 and N2 is not efficient; while it is obvious by SO2 because of its strong polarity. The size and volume of halogen atoms in the halomethane molecules play an important role in quenching SO(c1Σ－), and it seems that there is no evident correlation between the quenching rate constants and the number of the chlorine atom in the chlomethane molecules.
