Energy calculated at CCSD/Def2TZVPP
| | hartrees |
| Energy at 0K | -188.814592 |
| Energy at 298.15K | -188.815686 |
| HF Energy | -188.215070 |
| Nuclear repulsion energy | 63.347992 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
