Energy calculated at CISD/6-31G
| | hartrees |
| Energy at 0K | -2608.844596 |
| Energy at 298.15K | -2608.848161 |
| HF Energy | -2608.720726 |
| Nuclear repulsion energy | 78.123515 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
