Abstract: The fluorescence quenching spectra of p-chloraniline, using nitrobenzene and acetonitrile as quenchers in ethanol and p-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 (r) and the stern-volmer constant (Ksv) were calculated. The stoke’s shift, ionization potential, electron affinity and the solvent parameter (z) have also been calculated.
