The effect of the nature of the solvent on the luminescence spectra and lasing characteristics of laser- and flashlamp-pumped oxazine 17 has been studied experimentally. The solvatochromism and solvatofluorochromism of solutions of this activator are shown to be determined primarily by intermolecular interactions of a universal nonspecific nature. A method of functions of universal intermolecular interactions is used to show that the electronic excitation of the oxazine 17 molecule increases the dipole moment of this molecule to a value significantly larger than in the ground state. The threshold and energy characteristics of the lasing of ethanol solutions of oxazine 17 and rhodamine 6G are compared for various durations of flashlamp pumping. At comparatively long pump durations (approx.50 ..mu..sec) the lasing threshold of an ethanol solution of oxazine 17 falls below that of an ethanol solution of rhodamine 6G.
