In this paper,the reaction of NH 3 molecule and ground state NH radical is studied by the “direct dynamics” method of variational transition state theory,which uses the information on electronic structure energy and energy derivatives calculated ab initio along the minium energy path.
利用变分过渡态理论的“直接动力学”方法对ＮＨ３分子和基态ＮＨ（Ｘ３∑）自由基的反应进行了理论研究；利用从头算计算得到反应体系的电子结构能和能量梯度等信息，计算了２００～２５００Ｋ温度范围该反应的速率常数和穿透系数，分析了影响隧道效应和反应速率常数的一些因素。
Furthermore, the dynamical properties along the reaction path and CVT (canonical variational theory) rate constants with correction of tunneling effect are investigated by reaction path Hamiltonian theory and variational transition state theory.
用从头算ＵＨＦ／６－３１Ｇ方法计算ＣＨ３＋ＯＨ→ＣＨ２＋Ｈ２Ｏ的反应途径，在此基础上计算沿反应途径的动态学性质及正则变分过渡态理论的速率常数，同时进行隧道效应的校正。
