Energy calculated at QCISD/daug-cc-pVDZ
| | hartrees |
| Energy at 0K | -188.679211 |
| Energy at 298.15K | -188.680287 |
| HF Energy | -188.161386 |
| Nuclear repulsion energy | 62.597059 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
