Energy calculated at MP3/6-311+G(3df,2p)
| | hartrees |
| Energy at 0K | -188.799935 |
| Energy at 298.15K | -188.801050 |
| HF Energy | -188.205690 |
| Nuclear repulsion energy | 63.706671 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
