Energy calculated at MP2/6-31G
| | hartrees |
| Energy at 0K | -2608.829335 |
| Energy at 298.15K | -2608.832966 |
| HF Energy | -2608.720855 |
| Nuclear repulsion energy | 78.487222 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
