各位老师:
大家好!我用MOKIT将orca计算好的*.gbw轨道转化为局域配对UNO轨道,过程是先将*.gbw转为*fch,之后利用MOKIT读入。所有操作过程中都用的时全电子基组x2c-TZVPall,不涉及雁势。MOKIT输入文件如下:
1 %mem=360GB
2 %nprocshared=64
3 #p CASSCF/x2c-TZVPall
4
5 mokit{X2C,HFonly,readuhf=Sig.fch,ist=1}
6
7 1 3
8 Ir 5.36500000 8.21116300 10.13060500
9 S 3.52078000 9.84962100 6.35173200
10 S 5.79853600 7.94324900 14.61335800
。。。。。坐标省略,不到两分钟结束。之后将产生的局域配对UNO轨道*fch转化为*gbw,利用orca进行CASSCF计算,MOKIT计算出来的局域配对UNO轨道看着很合理,既能反应双自由基性质,也能显示出Ir的d轨道。出现警告。我的orca输入文件如下:
