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.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.
