在 248 nm 下面的本甲基氯化物( BzCl )的光致离解机制被计算地面( S0 )和更低的激动的状态的几何学被完全的活跃空间 SCF ( CASSCF )方法调查了,垂直(电视)并且断热( T0 )更低的状态的刺激精力,和 S1 , T1 和 T2 状态的势能表面(足)上的分离反应小径。计算结果清楚地阐明了 BzCl 的光致离解机制,并且显示 T1 状态的 PES 上的光致离解是最有利的。
The photodissociation mechanism of benzyl chloride (BzCl) under 248 nm has been investigated by the complete active space SCF (CASSCF) method by calculating the geometries of the ground (S0) and lower excited states, the vertical (Tv) and adiabatic (T0) excitation energies of the lower states, and the dissociation reaction pathways on the potential energy surfaces (PES) of SI, TI and T2 states. The calculated results clearly elucidated the photodissociation mechanism of BzCl, and indicated that the photodissociation on the PES of T1 state is the most favorable.
