In depicting reaction coordinates it is more customary to plot the free energy on the vertical axis . 在绘画反应坐标图时，较通行的是把自由能画在纵轴上。
2.
The ground state corresponds to a bent 2a " sno structure . the state - state correlation and the isomerization mechanism are also predicted by searching the transition states and the intrinsic reaction coordinate analysis 基态结构为弯曲的sno ( ~ 2a )结构，通过寻找过渡态和内禀反应坐标分析预测了各稳定态之间的态态相关和异构化机理。
