Energy calculated at CID/3-21G*
| hartrees |
Energy at 0K | -2599.240555 |
Energy at 298.15K | -2599.244306 |
HF Energy | -2599.032792 |
Nuclear repulsion energy | 79.672963 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
