The SO(X 3~-) product energy disposal in the desulfurization reaction of thiirane (C2H45) with O(3p) atom has been studied by probing its rovibrational state distributions via laser-induced fluorescence spectroscopy on the B 3E--X 3Etransition. The O(3p) atom was produced by 351 nm photolysis of NO

โฆ Synopsis
The rotational and vibrational energy distributions of S2(a 1~ and X 3y.~-) generated in the reaction ofS(3p 4, 1D) with thiirane C2H4S are measured, using the laser-induced fluorescence technique. Nascent energy distributions are approximated by Boltzmann distributions with rotational and vibrational temperatures: Trot = 3000--500 K and T,~b= 6000 K for $2 (a 1~,); Tot i> 4000 K and T~b = 1200 K for $2 (X 3Z~-). Relative product branching ratios from S (~D) + C2H4S under thermal collision conditions are estimated to be 0.14/0.30/0.56 for S2(a t~)/S2(X 3Z~-)/S(3p).
