Quantum Chemical Study on Mechanism of Reaction between O((3P)) and C2H2
【摘要】 用量子化学计算方法对O(3P)与C2H2的反应进行了研究.在HF/6311++G(d,p),HF/6311++G(3df,3pd),MP2/6311++G(d,p)和MP2/6311++G(3df,3pd)计算水平上,优化了反应势能面上各驻点的几何结构.通过内禀反应坐标(IRC)计算和振动分析,对反应过渡态进行了确认,并确定了反应机理.
【Abstract】 By means of quantum chemical study, the reaction between O((3P)) and C2H2 was studied. All the geometries at the critical points of the potential surface were completely optimized at the HF/6-311++G(d,p), HF/6-311++(3df,3pd), MP2/6-311++G(d,p) and MP2/6-311++G(3df,3pd) computational levels. All tranistion states are verified by the internal reaction coordinate calculations and the vibrational analysis. The mechanism of the reaction is confirmed.
