文摘

The effect of the concentration, temperature, and freezing rate on the spectra, kinetics, and intensity of phosphorescence of acenaphthene in polycrystalline n-hexane matrices has been studied. The specific features of the transformation of quasi-lines in the phosphorescence spectrum of molecules embedded in an n-hexane crystal lattice into broad molecular bands at high concentrations of the solution (~10‒1 mol/L) have been considered. It has been demonstrated that a distortion of the n-hexane crystal lattice at a high concentration of embedded acenaphthene molecules can be a cause of the observed transformation of the quasi-line spectrum.Original Russian Text © N.V.
