你看看帖子就知道了,就是你的计算没有收敛,
这不是你采用了opt=gdiis的方式来调节收敛了,
不收敛的问题分为两个:几何优化不收敛和scf不收敛。
我的建议是:(个人见解,不一定对哈)
1:opt=(maxstep=10,n ...

1.2.4都试了还是不行,只算OPT不算频率是同样的错误,这个结构是我先用B3LYP6-311+g(3df)算过的,你说先用小基组,但是我不知道比CBS-QB3小的基组是什么

It doesn't matter how slow you are, as long as you're determined to get there, you'll get there.
