Abstract
The fluorescence of naphthalene, benzene and twelve of its alkyl derivatives has been quenched by biacetyl in aerated normal hexane solution at 28°C. From the experimental quenching constants and the limiting rate constants computed for a diffusionally controlled quenching process, the lifetimes of the excited donors were obtained. These are shown to compare favorably with direct lifetime measurements (by phase shift) on the same materials.Keywords
