Energy calculated at CCSD(T)=FULL/aug-cc-pVDZ
| | hartrees |
| Energy at 0K | -2611.685307 |
| Energy at 298.15K | -2611.688783 |
| HF Energy | -2611.372653 |
| Nuclear repulsion energy | 80.089962 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
