The spectophotometry of charge transfer (CT) complexes of tetrachloro-p-benzoquinone (TCB) with tertiary amine [triethylamine (TEA), triphylamine (TPA), N,N-dimethylphenylamine (DMPA), N-ethylcarbazole (ECZ)] have been studied in dichloromethane in L1V-visible region. The CT complexes parameter, molar ratio of reactants in complex, molar extinction coefficient ε_CT, equilibrium constant K_CT, free energy 0G and dissociation energy of the CT complex excited state E, have also been estimated and discussed.
