C2+C2H2→C4H2反应机理的密度泛函研究
Density functional theory study on the reactionmechanism of C2 with C2H2
【摘要】 在密度泛函理论B3LYP/6-31+G水平上研究C2分子自由基与C2H2分子的反应机理。优化计算得到可能反应途径上的反应物、中间产物、过渡态和产物的几何结构,并通过频率振动分析对过渡态和中间产物进行了确认。结果表明,反应C2+C2H2→C4H2是多步骤的强放热反应。
【Abstract】 The reaction mechanism between C2 and C2H2 was investigated at B3LYP/6-31+G* level.The geometries of reactants,intermediates,transition states and product were optimized and verified by frequency analysis.The results indicate that the reaction C2+C2H2→ C4H2 is multi-step strong exotheric.
