The maxlmum Wavelength Value (λmax) of the Charge-Transfer Complexes of chloranil with aniline derivatives were measured in Cyclohexane. Compare to the aniline, the first and the second bands of aniline derivatives were found to be red shift. But the first bands were hardly affected by substituents, and the second bands were affected differently by the substituents on the donor molecule. They were assigned to the transition of an electron from, respectively, the highest occupied and the second highest occupied orbitals of the donor to the lowest unoccupied orbital of the acceptor. The locations of the first CT band were found to be extremely sensitive to variation in media, Therefore, the explation was arrived at by the use of a model where an acceptor was assumed to associate independently with several different sites of a donor molecule. Between the Value of the εmax and K of the aniline derivatives are not related each other, but εmax values are almost same in case of the derivatives of the donors are same site and substituent.
