## Abstract The dynamics of the concentration fluctuations in endβgrafted polystyrene brushes in a theta solvent (cyclohexane) are probed by evanescent wave dynamic light scattering at different wavevectors __q__ and temperatures. When the solvent quality changes from marginal to poor, the relaxati
intramolecular excimer formation in 2,4-diphenylpentanes has been examined in a homologous series of alkanes, in ethanol and in mixtures of ethanol, ethylene glycol and glycerol. The ratio of the emission intensities of dimer and monomer (ID/I.) is not affected in low viscosity solvents but, above 4
