Energy calculated at CCD/6-31G(2df,p)
| | hartrees |
| Energy at 0K | -114.175240 |
| Energy at 298.15K | -114.176663 |
| HF Energy | -113.800442 |
| Nuclear repulsion energy | 30.793011 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
