Energy calculated at CCSD(T)/6-31G*
| hartrees |
Energy at 0K | -2609.117328 |
Energy at 298.15K | -2609.121218 |
HF Energy | -2608.866550 |
Nuclear repulsion energy | 79.830274 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
