NMR, ABSORPTION AND FLUORESCENCE PARAMETERS OF AZLACTONES ICLI S, ICIL H, ALP S, KOC H, MCKILLOP A SPECTROSCOPY LETTERS 27 (9): 1115-1128 1994 Abstract: Absorption and fluorescence wavelenghts for a series of azlactones have been measured from acetonitrile solutions that had no pre-light exposure. Fluorescence quantum yields, Qf, are found to be in general less than 0.01, excluding the the derivatives with naphthyl and p-dimethylaminophenyl substituents. Previously reported Qf values did not fit to our results.
