Energy calculated at MP2=FULL/STO-3G
| | hartrees |
| Energy at 0K | -2583.222587 |
| Energy at 298.15K | -2583.226700 |
| HF Energy | -2583.174741 |
| Nuclear repulsion energy | 79.736875 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
