Energy calculated at ROHF/aug-cc-pVDZ
| | hartrees |
| Energy at 0K | -188.159477 |
| Energy at 298.15K | -188.160643 |
| HF Energy | -188.159477 |
| Nuclear repulsion energy | 64.125855 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
