Energy calculated at MP2/3-21G
| | hartrees |
| Energy at 0K | -485.580351 |
| Energy at 298.15K | |
| HF Energy | -485.300038 |
| Nuclear repulsion energy | 98.457018 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
