Abstract
Abstract The fluorescence behavior of 2-, 3- and 4-hydroxypridines has been studied in a variety of solvents. The most fluorescent form of the 2- and 3-isomers is the anion, which appears in 0.1 N NaOH, and fluoresces at shorter wavelengths than does the neutral molecule, indicating a decrease of acidity upon excitation. 4-hydroxypyridine was found to be non-fluorescent in all the solvents investigated. In all solvents studied the fluorescence yield is generally
