Energy calculated at LSDA/cc-pVTZ
| | hartrees |
| Energy at 0K | -113.861654 |
| Energy at 298.15K | -113.863062 |
| HF Energy | -113.861654 |
| Nuclear repulsion energy | 30.814002 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
