用量子化学密度泛函理论(DFT)和G3(MP2)B3方法,对O(1D)与CH2FCF3的反应进行了研究.在UB3LYP/6-31G(d)计算水平上,优化了反应势能面上各驻点的几何结构,在G3(MP2)B3水平上进行了单点计算,并利用UB3LYP/6-311++G(3df, 3pd)计算的波函数进行了电荷密度分析.通过内禀坐标(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.

By means of the density functional theory (DFT) and the G3(MP2)B3 method, the reaction between O(1D) and CH2FCF3 was studied.The geometries of the reactants, the transition states, and the products were completely optimized at the UB3LYP/6-31G(d) computational levels.The electronic densities were also computed at the UB3LYP/6-311++G(3df, 3pd) level.All the transition states were verified by the vibrational analysis and the IRC calculations.The mechanism of the reaction was confirmed.
