Energy calculated at CCSD/aug-cc-pVQZ
| hartrees |
Energy at 0K | -114.272501 |
Energy at 298.15K | -114.273920 |
HF Energy | -113.845562 |
Nuclear repulsion energy | 30.840874 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
