Energy calculated at QCISD/3-21G*
| hartrees |
Energy at 0K | -187.395009 |
Energy at 298.15K | -187.396008 |
HF Energy | -187.062566 |
Nuclear repulsion energy | 61.182672 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
