Energy calculated at CCSD/cc-pVDZ
| hartrees |
Energy at 0K | -114.126735 |
Energy at 298.15K | -114.128154 |
HF Energy | -113.799161 |
Nuclear repulsion energy | 30.523874 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
