Energy calculated at CCSD=FULL/TZVP
| | hartrees |
| Energy at 0K | -188.766092 |
| Energy at 298.15K | -188.767186 |
| HF Energy | -188.198623 |
| Nuclear repulsion energy | 63.300720 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
