Energy calculated at QCISD/3-21G
| | hartrees |
| Energy at 0K | -496.193799 |
| Energy at 298.15K | |
| HF Energy | -496.052020 |
| Nuclear repulsion energy | 42.629066 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
