Energy calculated at CCSD(T)/TZVP
| hartrees |
Energy at 0K | -114.188331 |
Energy at 298.15K | -114.189748 |
HF Energy | -113.832172 |
Nuclear repulsion energy | 30.615166 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
