Photolysis dynamics of benzyl phenyl sulfide adsorbed on silver nanoparticles
Article Abstract:
Results obtained with time-resolved transient-absorption spectroscopy to show the detailed photoreaction mechanism of BPS adsorbed on silver nanoparticles suspended in water is discussed. The benzenethiolate combines to the metallic surface of a silver nanoparticle in 30 ns while the benzyl radical abstracts atomic hydrogen from water in 130 ns to form toluence.

Photofragmentation dynamics of n-dodecanethiol-derivatized silver nanoparticles in cyclohexane
Article Abstract:
Photochemical reaction of n-dodecanethiol-derivatized silver nanoparticles in cyclohexane is studied in the picosecond-second time range and is found to depend nonlinearly on the irradiance of photolysis light. The static absorption bleach by excitation at 532 and 355 nm increases with the irradiance raised to the powers of 1.9 and 1.4, respectively.

Excited-state tautomerization dynamics of 7-hydroxyquinoline in beta-cyclodextrin
Article Abstract:
The excited-state tautomerization dynamics of 7-hydroxyquinoline in beta-cyclodextrin is compared with that in pure water by measuring isotope-dependent fluorescence kinetics as well as absorption and emission spectra. The normal species tautomerizes stepwise via forming anionic intermediate species in both systems.
