Energy calculated at MP2=FULL/TZVP
| | hartrees |
| Energy at 0K | -2611.835764 |
| Energy at 298.15K | -2611.839667 |
| HF Energy | -2611.405889 |
| Nuclear repulsion energy | 80.681057 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
