Energy calculated at QCISD(T)/aug-cc-pVDZ
| hartrees |
Energy at 0K | -114.165259 |
Energy at 298.15K | -114.166666 |
HF Energy | -113.808876 |
Nuclear repulsion energy | 30.298665 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
