Energy calculated at QCISD(T)/cc-pVTZ
| | hartrees |
| Energy at 0K | -114.252168 |
| Energy at 298.15K | -114.253582 |
| HF Energy | -113.834905 |
| Nuclear repulsion energy | 30.609297 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
