Energy calculated at CCD/TZVP
| | hartrees |
| Energy at 0K | -2611.769455 |
| Energy at 298.15K | -2611.773298 |
| HF Energy | -2611.405932 |
| Nuclear repulsion energy | 80.358388 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
