摘要

In this paper, a comprehensive analysis of the reaction H + O-2(a(1)Delta(g)) -> products and its channels, including available experimental data, theoretical estimations and kinetic studies, was carried out. A possible intrinsic mechanism of the reaction H + O-2(a(g)(1 Delta)) -> products, taking into account Renner-Teller coupling between the lowest doublet (2)A' and (2)A ''. states of a HO2 molecule was suggested. The proposed mechanism allows qualitative justification of the available data on the high probability for the quenching reaction: H + O-2(a(g)(1 Delta)) -> H + O-2((3)Sigma(g)). The effect of the reactions, including electronically excited HO2* molecules on the evaluation of temperature dependencies for the total and branching rate constants of the reaction H + O-2(a(1)Delta(g)) -> products at low temperatures, was investigated. The value of the reaction H + O-2(a(1) Delta(g))(+M) -> HO2((2)A', (2)A '')(+M) rate constant was evaluated from shock tube experiments on O-2(a(1)Delta(g)) quenching in a lean H-2-O-2-O-2(a(g)(1 Delta)) mixture. Based on the obtained results, temperature and pressure dependencies for the rate constants of the reaction H + O-2(a(1 Delta g)). product channels were recommended for the simulations, together with the proposed kinetic sub-mechanism for O-2(a(g)(1 Delta)) chemistry in H-2-O-2 mixtures.
