Dynamics and kinetics of the S + HO2 reaction: A theoretical study

Abstract: We report a quasi-classical trajectory study of the S + HO 2 reaction using a previously reported global potential energy surface for the ground electronic state of HSO 2 . Zeropoint energy leakage is approximately accounted for by using the vibrational energy quantum mechanical threshold method. Calculations are carried out both for specific ro-vibrational states of the reactants and thermalized ones, with rate constants being reported as a function of temperature. The results suggest that the title reaction … Show more

“…Thus, this work is aimed at studying the role of vibrational excitation energy of molecular oxygen in the reaction: (1) using the quasiclassical trajectory method and a global potential energy surface for the ground electronic state of HSO 2 , previously reported by one of us [18]. This methodology has already been used in previous studies concerning the HSO 2 molecular system [11,[19][20][21] furnishing good results when compared with the experimental data and new insights for the studied processes.…”

“…In previous papers of this series 16–18, we have reported quasi‐classical trajectory (QCT) studies of other reactions that occur on the adiabatic potential energy surface 19 for the ground electronic state of HSO 2 . Such studies have thus far led us to believe that the employed methodology allows a good description of the HSO 2 molecular system and the associated molecular reactions.…”

“…Mesmo quando estes resultados são obtidos do modelo simplificado apresentado, eles se ajustam muito bem a reações de tipo radical-radical [57] e descreve muito bem as colisões de tipo captura OH+SO [58] e S+HO 2 [59] , já estudadas.…”

“…O principal objetivo do presente trabalho é fazer um estudo teórico detalhado da fundamental já foi construída [98] e utilizada no estudo teórico de várias reações químicas [58,59,110,111] . Portanto, para o estudo da reação (4.2), no presente trabalho, é usada esta SEP e o método de trajetórias quase-clássicas [38] .…”
