Energy calculated at CBS-Q
| | hartrees |
| Energy at 0K | -2612.025422 |
| Energy at 298.15K | -2612.021199 |
| HF Energy | -2608.953663 |
| Nuclear repulsion energy | 80.316552 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
