Energy calculated at MP2=FULL/3-21G*
| | hartrees |
| Energy at 0K | -129.874133 |
| Energy at 298.15K | -129.876199 |
| HF Energy | -129.665675 |
| Nuclear repulsion energy | 33.838365 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
