 Alternatively, both electrons can remain in their degenerate ground state orbitals, but the spin of one can "flip" so that it is now opposite to the second (i.e., it is still in a separate degenerate orbital, but no longer of like spin); this also creates a new state, a singlet state referred to as the 1Σ state.The ground and first two singlet excited states of oxygen can be described by the simple scheme in the figure below.The 1Δg singlet state is 7882.4 cm−1 above the triplet 3Σ ground state., which in other units corresponds to 94.29 kJ/mol or 0.9773 eV.
