摘要

The rate constants for the H(2S) + H2S reaction were measured behind reflected shock waves (T = 1053-2237 K) and at 293 K, in which H(2S) atoms were generated by the ArF-laser photolysis of H2S. The resulting rate constant, k = (1.96 ± 0.7) × 10-17 T2.1±0.3 exp[- (352 ± 84) / T] cm3 molecule-1 s-1, showed a strong non-Arrhenius dependence on the temperature. This dependence is explained by a conventional transition-state theory combined with a quantum-mechanical calculation of the transition state at the PMP4(SDTQ)6-311G**//MP2/6-31G** level.
