Energy calculated at MP2=FULL/cc-pVDZ
| | hartrees |
| Energy at 0K | -2611.626283 |
| Energy at 298.15K | -2611.630227 |
| HF Energy | -2611.367921 |
| Nuclear repulsion energy | 80.556396 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
