[讨论交流] 请问大家electron orbital bind energy 用Gaussian 怎么计算?

那位高手请指点指点,electron orbital bind energy 用Gaussian 怎么计算?关键词OVGF怎么用?谢谢了!!
OVGF calculations default to storage of <ia||bc> integrals, but can be run Tran=Full to save CPU time at the expense of disk usage, or with Tran=IJAB to save on disk space at the expense of CPU time. In the latter case, electron affinities are not computed.

By default, only ionization potentials which are < 20 eV are computed.

使用MS、Gaussian
可是我用这个命令计算H2S的electron orbital bind energy ,H2S应该有18个电子,对应9个轨道的electron orbital bind energy ,可是用这个命令只得到2,3,4轨道的electron orbital bind energy ,我想请问的就是用什么命令可以得到全部的electron orbital bind energy ,谢谢了

谢谢楼主!学习了!
