The electronic absorption and fluorescence spectra of two isomeric anthracenecarboxamides substituted with quaternary alkyl ammonium groups were studied as a function of solvent polarity, solvent… (More)
Abstract Aldehydes and ketones derived from benzene are generally thought to phosphoresce but not to fluoresce (1). Although fluorescence has been observed from aldehydes and ketones derived from… (More)

An accurate UV spectrophotometric procedure was developed for the assay of aminobenzoic acid tablets. The crushed tablet was treated with 95% ethanol, and this alcoholic solution was diluted with… (More)
The electronic absorption and fluorescence spectra of 1-anthroic acid and 2-anthroic acid were studied throughout the pH range in aqueous buffers and the Hammett acidity range in sulfuric acid.… (More)
