Energy calculated at QCISD/6-31G**
| | hartrees |
| Energy at 0K | -114.112737 |
| Energy at 298.15K | -114.114153 |
| HF Energy | -113.790009 |
| Nuclear repulsion energy | 30.495840 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
