Energy calculated at CCSD/daug-cc-pVTZ
| | hartrees |
| Energy at 0K | -2611.869320 |
| Energy at 298.15K | |
| HF Energy | -2611.459074 |
| Nuclear repulsion energy | 81.040627 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
