Dissociative excitation of SO2,SOCl2 through single collision with Ar(3P0,2)have been studied by observing SO(A - X) emission in the beam apparatus. The nascent vibrational distribution of SO(A, υ＇) 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•molecule－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 monitor exit channels.
