Energy calculated at CCD/cc-pVTZ
| | hartrees |
| Energy at 0K | -2611.851910 |
| Energy at 298.15K | -2611.855520 |
| HF Energy | -2611.458325 |
| Nuclear repulsion energy | 80.992493 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
