III.D.10.

Calculated singlet - triplet Gaps for CCO (Dicarbon monoxide)

Vibrational zero-point energy (zpe) has not been included. Click on an entry for details including zpe.
singlet - triplet gaps in kJ mol-1.
Negative values indicate that the triplet state has a lower energy than the singlet state.
Methods with predefined basis sets
semi-empirical PM6  

Methods with standard basis sets
6-31G* TZVP
hartree fock HF -157 -157
density functional B3LYP   -104
