摘要：

Unusually large Stern-Volmer constants for the quenching of fluorescence of aromatic hydrocarbons by oxygen in solution are well known. The rate constants for the quenching reaction have been determined by fluorescence lifetime measurements for several hydrocarbons in a series of solvents covering a wide range of viscosities. The diffusion coefficient for oxygen in several solvents also was determined. The rate constants are consistent with a diffusion-controlled reaction when the unusually large diffusion coefficient for oxygen is taken into account.
