## Abstract Diffusion coefficients of camphorquinone (CQ) and its photoproduct (CQP) in two poly(methyl metbacrylate) (PMMA) samples with different molecular weights are measured as a function of temperature. Above the glass transition, the temperature dependence is not Arrhenius and can be describ
