Energy calculated at QCISD/6-311G**
| | hartrees |
| Energy at 0K | -188.699531 |
| Energy at 298.15K | -188.700635 |
| HF Energy | -188.181829 |
| Nuclear repulsion energy | 63.156669 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
