Calculated singlet - triplet Gaps for OH+ (hydoxyl cation)

18 11 02 13 31
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.
