Energy calculated at MP2/6-31G(2df,p)
| | hartrees |
| Energy at 0K | -2609.343182 |
| Energy at 298.15K | -2609.346973 |
| HF Energy | -2609.053535 |
| Nuclear repulsion energy | 81.645722 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
