Energy calculated at CID/3-21G*
| hartrees |
Energy at 0K | -187.357722 |
Energy at 298.15K | -187.358784 |
HF Energy | -187.065504 |
Nuclear repulsion energy | 61.952401 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
