Energy calculated at QCISD(T)/aug-cc-pVDZ
| hartrees |
Energy at 0K | -130.807109 |
Energy at 298.15K | |
HF Energy | -130.418614 |
Nuclear repulsion energy | 34.816419 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
