然后就一步一步计算先算了基态#p opt freq b3lyp/6-31g(d,p)出来一样的图,接着算了三重激发态#p opt freq td b3lyp/6-31g(d,p)自旋多重度哪里选了Triplet计算的结果跟图片就不太一样跟基态差不多就是C-O变成单键了,我想知道这里算错了吗,接着out文件调整一下C-C键算TS不能算,因为Force Constant不能选择,但是我用基态的构型中选了Triplet优化完后调整一下C-C键进行TS计算#p opt=(calcall,ts,noeigen) freq b3lyp/6-31g(d,p)就可以得到的跟图中的振动模式一样,然后就根据这个进行IRC计算#p irc=(calcfc,maxpoints=200,recalc=3) b3lyp/6-31g(d,p)就报错了
