Energy calculated at QCISD/aug-cc-pVTZ
| | hartrees |
| Energy at 0K | -114.246065 |
| Energy at 298.15K | -114.247480 |
| HF Energy | -113.837839 |
| Nuclear repulsion energy | 30.695208 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
