Resumo: | Quasiclassical trajectory calculations have been carried out for the reaction S + O2 → SO + O and its reverse using an accurate single-valued double many-body expansion (DMBE) potential energy surface previously reported for the ground electronic state of the sulfur dioxide molecule. A new scheme is suggested for thermalization of the reactants which avoids the usual separation of rotation and vibration. A detailed analysis of complex formation and thermal energy distribution in the products is also presented for the direct reaction at T = 300 K. The agreement with experimental data is satisfactory. |
