基于从头算数据拟合得到的新的基态势能面,对气相反应N(4^S)+O2(X^3∑g^-)→NO(X^2Π)+O(3^P)进行了系统的准经典轨线研究.文中计算了该反应的反应几率、反应截面以及在T=300、500、700 K时的热速率常数.通过与以前的理论值和实验值比较发现,我们算得的结果与实验值符合得很好.
A quasiclassical trajectory study on the N(4^S)+O2(X^3∑g^-)→NO(X^2Π)+O(3^P) atmospheric reaction has been performed by employing a new ground potential energy surface. The reaction probability, the reaction cross-section and the thermal rate constants at T = 300, 500, and 700 K for the reaction have been evaluated, and it is indicated by comparison that the thermal rate constants calculated in this work agree well with the experimental data.
