Energy calculated at ROHF/Def2TZVPP
| | hartrees |
| Energy at 0K | -188.212790 |
| Energy at 298.15K | -188.213959 |
| HF Energy | -188.212790 |
| Nuclear repulsion energy | 64.444293 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
