PRIMARY PROCESSES AND ENERGY DISPOSAL IN THE REACTION OF S((1)D) ATOMS WITH THIIRANE

The rotational and vibrational energy distributions of S2(a 1DELTA(g) and X3SIGMA(g)-) generated in the reaction of S(3p4, 1D) with thiirane C2H4S are measured, using the laser-induced fluorescence technique. N ascent energy distributions are approximated by Boltzmann distribution s with rotational and vibrational temperatures: T(rot) = 3000 +/- 500 K and T(vib) = 6000 K for S2(a 1DELTA(g)); T(rot) greater-than-or-equa l-to 4000 K and T(vib) = 1200 K for S2(X 3SIGMA(g)-). Relative product branching ratios from S(1D) + C2H4S under thermal collision condition s are estimated to be 0.14/0.30/0.56 for S2(a 1DELTA(g))/S2(X 3SIGMA(g )-)/S(3P).
