Energy calculated at CCSD(T)=FULL/cc-pVTZ
| hartrees |
Energy at 0K | -114.278138 |
Energy at 298.15K | -114.279555 |
HF Energy | -113.835409 |
Nuclear repulsion energy | 30.741183 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
