Two small groups ( E,σ_v) and ( E, C_2) are used to discuss the whole reaction paths of the suprafacial and the antarafacial sigmatropic reactions respectively.
本文用两个小群（E，σv）和（E，C2）分别讨论σ键迁移的同面反应和异面反应。
Based on the discussions of MO Following and the bond order change between the designed pairs of basis orbitals on excitation, the most reasonable ring-opening mode of the title compound appeared to be the direct suprafacial 1, 3-hydrogen migration.
基于分子轨道跟踪法和激发分子基础轨道对间的键序变化讨论.标题化合物最合理的开环模式是同面的1,3氢迁移。
There is no symmetry throughout the reaction process of [ 1, n] sigmatropic rearrangements except in the transition state, in which the suprafacial process is of C symmetry, while the antarafacial one is C_2 ( Fig, 1).
[1，n]σ迁移反应除了过渡态外整个反应过程不具对称性。同面过程的过渡态有C1对称性，异面过程的有C2对称性。
