Energy calculated at MP2/6-311G*
| | hartrees |
| Energy at 0K | -488.441933 |
| Energy at 298.15K | |
| HF Energy | -487.953251 |
| Nuclear repulsion energy | 99.851511 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
