Energy calculated at HF/CEP-31G
| | hartrees |
| Energy at 0K | -26.418893 |
| Energy at 298.15K | -26.421127 |
| HF Energy | -26.418893 |
| Nuclear repulsion energy | 20.825989 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
