Energy calculated at CCSD/TZVP
| | hartrees |
| Energy at 0K | -130.820701 |
| Energy at 298.15K | |
| HF Energy | -130.444808 |
| Nuclear repulsion energy | 35.079674 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
