Energy calculated at CISD/6-31G
| | hartrees |
| Energy at 0K | -113.928063 |
| Energy at 298.15K | -113.929468 |
| HF Energy | -113.727347 |
| Nuclear repulsion energy | 29.890884 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
