Energy calculated at CCSD/cc-pVTZ
| | hartrees |
| Energy at 0K | -130.888004 |
| Energy at 298.15K | |
| HF Energy | -130.447698 |
| Nuclear repulsion energy | 35.244809 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
