Solvent effects on the ability of amines to physically quench singlet oxygen as determined by time-resolved infrared emission studies

The rates of physical quenching of singlet oxygen by nine amines were determined by following the decrease in the singlet oxygen emission intensity at 1270 nm. The effect of solvents on these rates were shown to be related to the hydrogen bond donating ability of the solvent, {alpha}.
