Energy calculated at MP2/6-31G**
| | hartrees |
| Energy at 0K | -2609.101191 |
| Energy at 298.15K | -2609.105202 |
| HF Energy | -2608.870836 |
| Nuclear repulsion energy | 80.412103 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
