摘要：
3-amino-N-methylphthalimide (3ANMP) in a binary solvent (decaline + ethanol additions) has been investigated. Experiments were performed using equipment with nanosecond time resolution and luminescence excitation in different regions of the absorption spectrum. The obtained results point to the existence of dynamic inhomogeneous broadening of electronic spectra of three-component solutions (TCS) which appears as the dependence of spontaneous emission spectra on the excitation frequency at the first moments after excitations. A complicated nonexponential picture of TCS spectrochronograms transformation has been observed which can not be attributed to the translational diffusion of polar molecules from solution to solvate alone. A new interpretation of the dynamics of molecular processes in three-component solutions taking into account both translational and orientational motion of solvate molecules is proposed. © 1990.
