Energy calculated at CCSD(T)=FULL/cc-pVQZ
| | hartrees |
| Energy at 0K | -114.345393 |
| Energy at 298.15K | -114.346810 |
| HF Energy | -113.844566 |
| Nuclear repulsion energy | 30.805158 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
