Energy calculated at QCISD(T)/aug-cc-pVTZ
| hartrees |
Energy at 0K | -2611.883423 |
Energy at 298.15K | |
HF Energy | -2611.458965 |
Nuclear repulsion energy | 80.867079 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
