Some Spectroscopic and Thermodynamic Studies of Charge Transfer


The π→π* charge transfer(CT) complexes of 2,3-dichloro-5,6-dicyanobenzoquenone(DDQ) with some phenol derivatives have been investigated spectraphotometrically inchloroform solution. The equilibrium constant (K) and extinction coefficient (ε) and thedissociation energies of the complexes excited state (w) of charge transfer have been calculatedand discussed. The ionization potential of phenol derivatives have estimated.
