【摘要】 利用化学发光方法研究了Ar（3P0,2）与SO2，SOCl2在单次碰撞条件下SO（A）的形成动力学，通过对实验光谱进行曲线拟会，得到了SO（A，υ＇）的初生态布居．分别是N0：N1：N2：N3：N4：N5：N6＝1．00：0．670．57：0．55：0．50：0．35：0．30和1．00：0．69：0．61：0．53：0．40：0．34：0．26．利用参考反应法求算了SO（A）的形成速率，分别为：4．55×10－12cm3·molecule－1·s－1和2．87×10－12cm3·molecule－1·s－1，与总猝灭速率相比较，发现解离激发为反应的次要出口通道．通过惊奇度分析，对激发解离机理进行了讨论．更多还原

【Abstract】 Dissociative excitation of SO2,SOCl2 through single coilision with Ar(2P0,2)have been studied by observing SO(A - X) emission in the beam apparatus. The nascent vibrational distribution of SO(A, v’) was determined. A Surprisal analysis of the nascent vibrational distribution of SO(A) indicated that the precursor molecules dissociation could occur predominately from superexcited states (Rydberg-states). The formation rate constants of SO(A) have been determined for Ar(3P0,2)/SO2 and Ar(3P0,2)/SOCl2 reactions,They are: 4.55 × 10-12cm3 ·molcule-1·s-1 and 2.87 × 10-12cm3·molecule-1 ·s-1, respectively.A comparison between the observed formation rate constants and known total quenching rate constants indicated that dissociative excitation processes are minor exit channels.更多还原
