Fluorescence quenching spectra of <i style="">p</i>-chloranilne and <i style="">p</i>-toluidine

Abstract

The fluorescence quenching spectra of <i style="">p</i>-chloraniline, using nitrobenzene and acetonitrile as quenchers in ethanol and <i style="">p</i>-toluidine, using benzoic acid and carbon tetrachloride as quenchers in chloroform have been obtained. The stern-volmer constants for all quenching process have been plotted. The regression analysis for stern-volmer plot has been carried out. Regression coefficient (<i style="">r</i>) and the stern-volmer constant (<i style="">K</i>_sv) were calculated. The stoke’s shift, ionization potential, electron affinity and the solvent parameter (<i style="">z</i>) have also been calculated.
