DFT Study on the Reaction Mechanism of BrONO2 and Br(2P3/2)
【摘要】 采用密度泛函理论计算方法B3LYP和基组6 31G(d),对BrONO2+Br(2P3/2)的反应机理进行了理论计算,得到各种可能反应途径的过渡态,并经过频率振动分析和内禀反应坐标(IRC)分析加以确认。结果表明:该反应是3通道反应,其中BrONO2+Br→Br2+NO3的反应活化能(5.25kJ/mol)最低,是反应主通道。
【Abstract】 Reaction mechanism of BrONO2 and Br (2P3/2) was studied by the use of B3LYP/6-31G(d) method. Transition state of various possible reaction pathways were obtained and verified by frequency analysis and intrinsic reaction coordinate (IRC) analysis. Result showed that the reaction was a three-channel complex and activation energy of the main reaction BrONO2+Br(3/2)→Br2+NO3?was 5.25?kJ/mol, which was the lowest.
