The Quenching of Singlet Molecular Oxygen

The relaxation of electronically excited molecules can occur by the emission of radiation and by several non-radiative pathways. Knowledge of both types of events is essential to the complete understanding of chemiluminescent and photochemical systems since together they determine “quantum efficiencies”. Radiative processes are reasonably well understood for most molecules. In the case of oxygen, some novel energy-pooling radiative processes have been observed (1), but these are now reasonably well understood. The major focus of this paper is the non-radiative processes, about which considerably less is known.
