Energy calculated at CCD/aug-cc-pVTZ
| hartrees |
Energy at 0K | -114.240941 |
Energy at 298.15K | -114.242361 |
HF Energy | -113.838190 |
Nuclear repulsion energy | 30.815357 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
