Energy calculated at CCSD(T)=FULL/aug-cc-pVQZ
| | hartrees |
| Energy at 0K | -116.562141 |
| Energy at 298.15K | |
| HF Energy | -115.915884 |
| Nuclear repulsion energy | 58.796145 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
