Rate constants for the decay and reactions of the lowest electronically excited singlet state of molecular oxygen in solution

The available rate data on the reactivity and physical deactivation of molecular oxygen in its first electronic excited state (1Δg) in liquid solution have been critically compiled. Where possible, relative rates reported in the literature have been normalized to standard values selected by a statistical analysis of the experimental data. Second order rate constants for the deactivation and chemical reaction of singlet oxygen are reported for 670 compounds. Additionally, psuedo first order rate constants (kd) for solvent deactivation of singlet oxygen are reported for 50 different solvents.
