Energy calculated at CCD/aug-cc-pVTZ
| | hartrees |
| Energy at 0K | -90.416362 |
| Energy at 298.15K | -90.416172 |
| HF Energy | -90.138649 |
| Nuclear repulsion energy | 17.475383 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
