| Abstract | The kinetics have been studied for two processes whose limiting stage is the diffusion of molecular oxygen: (i) oxidation of radicals after irradiation; and (ii) quenching of phenanthrene phosphorescence. The processes were studied in glassy squalane and poly(methyl methacrylate) matrices. Comparison between the kinetic properties of these processes allowed us to conclude about predominant stabilization of radicals near structural defects of glass. In squalane this manifests itself in anomalously high value of reaction radius for oxidation of radicals and in poly(methyl methacrylate) in quantitative difference in the parameters of distribution in rate constants for processes (i) and (ii). |
