Energy calculated at QCISD(T)/aug-cc-pVDZ
| hartrees |
Energy at 0K | -2611.673723 |
Energy at 298.15K | -2611.677375 |
HF Energy | -2611.372663 |
Nuclear repulsion energy | 79.970624 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
