Abstract A general equation is derived from the light output of a liquid scintillator as a function of solute concentration, which includes both radiative and nonradiative excitation energy transfer. The rate constants for energy transfer from toluene to 2,5-diphenyloxazole, anthracene, 9,10diphenylanthracene, pe rylene, and methyl anthranllate, were determined from the equation using oxygen-quenching data obtained by gamma -ray and uv excitation. The correction of the observed scintillation intensities for reabsorption and reemission of solute fluorescence is described. The corrected points were found to agree well with the general equation using transfer rate constants derived from oxygen- quenching studies.
