Ground state dipole moment of the charge transfer complexes of some aromatic hydrocarbons with chloranil from solvent shift data

Abstract

The ground state dipole moment of charge transfer complexes of chloranil with aromatic hydrocarbons has been calculated as a linear function of solvent shift. Very close values of <em>μ</em>₁ and <em>μ</em>₂ for multiple charge transfer bands indicate that orientation is not playing a major role. The weak nature of the complexes is manifested by the oscillator strength values. Nevertheless lower energy transition shows a greater overlap.
