Energy calculated at QCISD/aug-cc-pVTZ
| | hartrees |
| Energy at 0K | -2611.867861 |
| Energy at 298.15K | -2611.871482 |
| HF Energy | -2611.459003 |
| Nuclear repulsion energy | 80.978362 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
