Abstract :The UV-visible absorption bands of the new complex were obtained using p-amino-N, N-dimethyl aniline as an electron donor with ferric nitrate as an electron acceptor in methanol at 25°C. The values of association constant KAD, molar extinction coefficient \varepsilonAD, and absorption band energy of charge transfer complex h \varepsilonCT were calculated. The ionization potential of the donor ID, was calculated from the complex band energy. The kinetics of the above association reaction were studied. This reaction was found to be a first order. The values of the rate constant of the forward reaction k1, the rate constant of the reverse reaction k-1, and the half-life t1 / 2 were calculated.Keywords : UV-visible spectrophotometry, charge transfer complex, Benesi-Hildebrand, Scott, Foster-Hammick-Wardley, association constant, molar extinction coefficient, ferric nitrate, methanol.
