Energy calculated at MP2/CEP-121G
| | hartrees |
| Energy at 0K | -35.479390 |
| Energy at 298.15K | |
| HF Energy | -35.325607 |
| Nuclear repulsion energy | 29.793134 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
