The spectral luminescence and lasing (lasing frequency, lasing threshold) parameters of 3- and 4-amino-N-methyl phthalimide in mixed nonpolar or weakly polar and polar solvents were compared with the values characterizing the intermolecular relaxation processes in the solution. It was demonstrated that, in accordance with concepts developed, a clear dependence of the threshold on the magnitude of the energy gap between the ground equilibrium and Franck--Condon electronic states of the activator molecule in the solution is observed: the greater the energy gap, the lower the lasing threshold, and vice versa. A preliminary evaluation of some experimental data that testify to the substantial effect of the statitistical intermolecular processes on the lasing parameters of multicomponent solutions is offered.
