β¦ Synopsis
numbers of studies were performed until very recently on the fundamental oxidation reaction mechanism of hydrogen sulfide and related H 9 S 9 O reaction systems.
The oxidation process of H 2 S (and some times the catalytic effect of SO 2 ) have been investigated in several flame studies [1 -5], and the reaction mechanisms were discussed based on the measured product distributions. These studies have provided much useful information on the elementary reactions of H 9 S 9 O systems, however, it is generally very difficult to judge the reliability of kinetic/thermodynamic parameters of individual elementary reactions proposed in these indirect studies. It is also noted that even a conventional shock tube study was not performed for clarifying oxidation mechanism of H 2 S (as far as we know), except an ignition delay mea-

The reaction Y + + NH, + Y'NH + H, was theoretically investigated by ab initio MO methods. Two possible pathways (1-1 H, loss and 1-2 H, loss) on the singlet potential energy surface and reaction mechanism were examined and discussed. The singlet and triplet PESs of this reaction system were compare
