Energy calculated at QCISD/6-311G*
| | hartrees |
| Energy at 0K | -188.685888 |
| Energy at 298.15K | -188.687001 |
| HF Energy | -188.174490 |
| Nuclear repulsion energy | 63.140700 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
