Abstract
The previously developed approach to the analysis of experimental spectra of non-stationary fluorescence has been improved by taking into account the effect of the duration of the gating pulse and a more accurate description of the initial stage of solvent relaxation. The exponential function used to describe the inertial component of relaxation has been replaced by the Gaussian function. This approach explicitly takes into account the reorganization and relaxation of the solvent and intramolecular vibrations. It includes an explicit description of the wave packet formation in the excited state of the fluorophore. The improvement of the approach made it possible to refine the relaxation characteristics of a number of solvents: ethylene glycol, dimethyl sulfoxide, butyronitrile, ethyl acetate, diethyl ether, dipropyl ether. Keywords: nonequilibrium of the nuclear subsystem, Stokes shift, relaxation of intramolecular vibrations, inertial component of solvent relaxation
