A Density Functional Theory(DFT) Study on the Reaction of Ozone with Ethylene Radicals
【摘要】 采用密度泛函B3LYP/6-311G水平计算研究了O3氧化乙烯基(C2H3)的机理,全参数优化了反应势能面上各驻点的几何构型,用内禀反应坐标(IRC)计算和频率分析方法,对过渡态进行了验证.结果表明,乙烯基(C2H3)与O3之间有很强的反应活性.
【Abstract】 The reaction mechanism between ozone and ethylene radical (C2H3) has been studied using the density functional theory ( DFT ) at B3LYP/6-311Glevel.The geometries for reactants,the transition states and the products were completely optimized.All the transition states are verified by the vibrational analysis and the intrisic reaction coordinate ( IRC ) calculations.The results show that the ethylene radical (C2H3) trends intensively to react with the ozone.
