Energy calculated at CCSD(T)/cc-pVDZ
| | hartrees |
| Energy at 0K | -130.765498 |
| Energy at 298.15K | |
| HF Energy | -130.403545 |
| Nuclear repulsion energy | 34.948437 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
