Energy calculated at CCSD/aug-cc-pVTZ
| hartrees |
Energy at 0K | -188.820973 |
Energy at 298.15K | -188.822067 |
HF Energy | -188.208713 |
Nuclear repulsion energy | 63.285000 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
