Energy calculated at CCSD/TZVP
| hartrees |
Energy at 0K | -188.713585 |
Energy at 298.15K | -188.714677 |
HF Energy | -188.198494 |
Nuclear repulsion energy | 63.258845 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
