Energy calculated at CCSD(T)=FULL/daug-cc-pVTZ
| | hartrees |
| Energy at 0K | -207.753197 |
| Energy at 298.15K | |
| HF Energy | -206.870977 |
| Nuclear repulsion energy | 104.092859 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
