Energy calculated at CCD/6-31G*
| | hartrees |
| Energy at 0K | -188.589469 |
| Energy at 298.15K | -188.590577 |
| HF Energy | -188.125309 |
| Nuclear repulsion energy | 62.927379 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
