Singlet oxygen - Wikipedia

The 1 Δ g singlet state is 7882.4 cm −1 above the triplet 3 Σ − g ground state., which in other units corresponds to 94.29 kJ/mol or 0.9773 eV. The 1 Σ + g singlet is 13 120.9 cm −1 (157.0 kJ/mol or 1.6268 eV) above the ground state.. Radiative transitions between the three low-lying electronic states of oxygen are formally forbidden as electric dipole processes.

Singlet Oxygen: Generation and Properties - photobiology
