WebbUnlike the case of the simpler situation above, the physical process that best approximates what is happening along the reaction coordinate changes from stage to stage across the diagram. The highest point on the energy diagram corresponds to the energy of the transition state of the rate-limiting step in the reaction—that is, the slowest step in the … WebbFör 1 timme sedan · 进行过渡态搜索的时候，我的生成物都是从反应物的构型复制过来的基础上改动再进行优化的，但是在搜索过渡态时出现了“Fixed atom coordinate mismatch Fixed atom coordinates should match to within 0.00010”的错误，不知道哪里出了问题。希望大神们可以帮忙解决一下！
