Energy calculated at HF/SDD
| | hartrees |
| Energy at 0K | -113.756573 |
| Energy at 298.15K | -113.757989 |
| HF Energy | -113.756573 |
| Nuclear repulsion energy | 30.368541 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
