Field diagram for a molecule appearing in charge transfer state in polar solution

A theoretical consideration of potential energy of a molecule appearing in charge transfer state has been performed and the expressions for potential energy of the S0 and the S1 states versus the strength of reaction field of the solvent have been derived. The field diagram plotted on the basis of these expressions represents, in a natural way, inhomogeneous broadening of electronic spectra for charge transfer systems in a solution where this factor is of great importance. The accounting of the charge transfer process was carried out treating it formally as a permanent growth of the excited state electric dipole moment of the solute with the strength of its reaction field. The field diagram of the S0 and the S1 singlet states and appropriate probability distributions over different fields of reaction was shown to open a door for describing the basic properties of molecules appearing in charge transfer states taking into account inhomogeneous broadening of its spectra.
