Abstract

The fluorescence quenching spectra of aniline and <i>p</i>-toluidine using picric acid as a quencher in methanol have been studied. The stern -volmer constants for all the quenching processes have been plotted. Regression analysis for stern- volmer plot has been carried out Regression coefficient <i>( r) </i>and the stern- volmer constant (<i>K</i>_sv) have been calculated. Stoke’s shift ionization potential,
