Energy calculated at CCSD(T)/6-31G(2df,p)
| | hartrees |
| Energy at 0K | -166.188890 |
| Energy at 298.15K | |
| HF Energy | -165.666112 |
| Nuclear repulsion energy | 49.034690 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
