Energy calculated at MP3/cc-pVTZ
| | hartrees |
| Energy at 0K | -90.408056 |
| Energy at 298.15K | -90.407915 |
| HF Energy | -90.136390 |
| Nuclear repulsion energy | 17.514483 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
