Abstract
A new approach is formulated to the solution of the crucial problem associated with developing the optimum methodology for quantitatively analyzing large arrays of experimental data relating to the optical spectra of solutions of polar organic dyes in a wide set of individual solvents of various chemical natures. The approach is based on the analytical relations of the semi-empirical theory proposed earlier by one of the authors and makes it possible for the first time to calculate all the main components of the absolute solvation shift of the absorption and fluorescence spectra of solutions during a gas-solution transition. This approach makes it possible to propose extremely simple working formulas that are convenient in practice for finding the collection of electric, optical, and structural characteristics of the dye molecule in the excited electronic state from the spectroluminescence data.
