Energy calculated at MP2=FULL/cc-pVTZ
| | hartrees |
| Energy at 0K | -2611.891633 |
| Energy at 298.15K | |
| HF Energy | -2611.458035 |
| Nuclear repulsion energy | 81.660934 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
