Energy calculated at MP2=FULL/STO-3G
| hartrees |
Energy at 0K | -149.250912 |
Energy at 298.15K | |
HF Energy | -149.114591 |
Nuclear repulsion energy | 50.797202 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
