Energy calculated at CCD/aug-cc-pVDZ
| | hartrees |
| Energy at 0K | -188.665112 |
| Energy at 298.15K | -188.666202 |
| HF Energy | -188.161166 |
| Nuclear repulsion energy | 62.831847 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
