The relative fluorescence efficiencies of anthracene in various solvents have been determined, and after correcting for several sources of error differences are still present. Minor uncertainties are present owing to bending of light at the face of the fluorescence cell.pdfen-NZAnthaceneFlorescenceChemistryText
