Energy calculated at ROHF/cc-pVDZ
| | hartrees |
| Energy at 0K | -2611.368222 |
| Energy at 298.15K | -2611.372265 |
| HF Energy | -2611.368222 |
| Nuclear repulsion energy | 79.979953 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
