Energy calculated at CCSD(T)/6-31G*
| | hartrees |
| Energy at 0K | -114.099662 |
| Energy at 298.15K | -114.101075 |
| HF Energy | -113.781411 |
| Nuclear repulsion energy | 30.378277 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
