Product energy disposal in the nonadiabatic reaction S(1D) + CS2 --> S2 (X3Σ-g) + CS (X1Σ+)

Article abstract of DOI:10.1063/1.461805

The product energy disposal in the reaction S(¹D) + CS2 --> S2 +CS is measured via laser-induced fluorescence.Molecular sulphur is produced exclusively in its electronic ground state (³Σ^-_g) with up to 3 quanta of vibrational excitation and rotational excitation that roughly approximates a 1000 K Boltzmann distribution.The CS produced from the reaction is formed predominantly in its vibrationless state.The total internal energy content of the product molecular sulphur is only about 12percent of the total available energy of the reaction: the CS fragment also has minimal internal energy, implying that most of the reaction energy resides in product translation.These results are different from those observed in the isovalent S + OCS reaction and suggest that a different detailed mechanism is operative.
