Energy calculated at CCD/aug-cc-pVTZ
| | hartrees |
| Energy at 0K | -188.813190 |
| Energy at 298.15K | -188.814295 |
| HF Energy | -188.209197 |
| Nuclear repulsion energy | 63.429485 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
