Energy calculated at CCD/6-31+G**
| | hartrees |
| Energy at 0K | -114.119367 |
| Energy at 298.15K | -114.120788 |
| HF Energy | -113.798464 |
| Nuclear repulsion energy | 30.653391 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
