Energy calculated at MP2=FULL/cc-pVDZ
| | hartrees |
| Energy at 0K | -90.319831 |
| Energy at 298.15K | -90.319622 |
| HF Energy | -90.102587 |
| Nuclear repulsion energy | 17.253029 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
