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.

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
