NLMO program cannot always handle this situation.
Illegal range for read: IUnit= 7 Address= -128 Length= -128 File length= 239616.
Error termination in NtrErr:
NtrErr called from NtrIO.

其他基组如:6-311+G,6-311+G(d),6-311+G(d,p),6-311G(d)也试过了,但是也报错,请问这是什么原因?输入输出文件见附件
我的推测:Degeneracy between orbitals in the (a) and (b) sets detected;NLMO program cannot always handle this situation.这个应该是因为NBO程序自身的bug,NLMO计算不能处理轨道简并,因此报错。
该体系是阳离子体系,不能加弥散函数,会对希尔伯特空间下的波函数分析方法造成严重不良影响,导致NLMO识别出错。
