Energy calculated at MP2/cc-pVDZ
| | hartrees |
| Energy at 0K | -90.315422 |
| Energy at 298.15K | |
| HF Energy | -90.101882 |
| Nuclear repulsion energy | 17.440612 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
