Energy calculated at QCISD/cc-pVDZ
| | hartrees |
| Energy at 0K | -498.771162 |
| Energy at 298.15K | |
| HF Energy | -498.486168 |
| Nuclear repulsion energy | 44.905211 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
