Energy calculated at MP2/CEP-31G*
| | hartrees |
| Energy at 0K | -21.519774 |
| Energy at 298.15K | |
| HF Energy | -21.287486 |
| Nuclear repulsion energy | 15.789987 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
