Energy calculated at CCSD/cc-pVTZ
| | hartrees |
| Energy at 0K | -115.705148 |
| Energy at 298.15K | -115.706820 |
| HF Energy | -115.234476 |
| Nuclear repulsion energy | 58.020786 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
