✦ Synopsis

Picosecond time-resolved total internal reflection fluorescence spectroscopy was applied lo analyze the proton transfer reaction of I-naphthol in water-sapphire interface layers. The rate constant of the proton transfer reaction from excited neutral species became slow in the interface layer as compared with that in the bulk aqueous solution. The anomaly observed up to the penetration depth of 100 nm was interpreted in terms of rotational fluctuations of water aggregates in the interface layer.

By means of time-resolved total internal reflection (TIR) fluorescence measurements, rise and decay profiles of the pyrene excimer fluorescence were examined in toluene containing 3.3x 10e4 mol dm-" of poly(methy1 methacrylate) (PMMA, MW= 120000). In addition to a reduction of the fluorescence inten
