Abstract :Charge-transfer complexes of 2,3-dichloro-5, 6-dicyano-p-benzoquinone insert ignore into journalissuearticles values(DDQ); p-acetotoluidide, acetanilid, biphenyl and naphthalene were studied and their absorption spectra in solution were recorded. Absorption spectral data were obtained in CH2Cl2, CHCl3, CCl4 and mixture insert ignore into journalissuearticles values(CH2Cl2 + V); at different temperatures. Two charge-transfer bands were observed in each case. Spectral characterization of these complexes was determined and correlated with the ionization potential of the donor. Variation in thermodynamic parameters were also found to be due to change in donor and solvent.
