Excitation spectra of anthracene were recorded in the temperature range 80 -270 K in various frozen aqueous solutions containing the surfactants cetyltrimethylammonium halide CTAX (X = F, Cl, Br, I) or alkali dodecylsulphate MDS (M = Na, Cs). Fluorescence quantum yields (relative values) were obtain
The fluorescence from the St state of pyrene solubilized within the hydrophobic region of sodium dodecyl sulfate micelles has been studied as a function of concentration of some cationic additives to the aqueous phase. At concentrations of added quencher below ca\_ 10v3 mol dm -3 the fluorescence de
