Energy calculated at ROHF/6-311G*
| | hartrees |
| Energy at 0K | -2611.356672 |
| Energy at 298.15K | -2611.360725 |
| HF Energy | -2611.356672 |
| Nuclear repulsion energy | 80.087967 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
