Abstract
The paper presents the general model describing the absorption and emission phenomenon of the fluorescent probe molecules showing the local excited and charge transfer electronic state. We reveal the complex character of inhomogeneous broadening of the charge transfer band in solutions, where, at least, three major mechanisms are responsible for this phenomenon. The distribution of molecules describing relative orientations of the twisting moiety in respect to the basic plane of the molecule is one of the important factors, contribution to the spectral displays. It is shown that this distribution depends on the space structure of the molecule as well as on the excitation wavelength. These factors create an opportunity to appear various red edge effects at proper conditions in a solution. As an example for such modeling the experimental data obtained for laurdan probe molecules in glycerol are used.
