The back proton recombination following the photo-dissociation of 1-naphthol was studied by a time-correlated single-photon counting apparatus. The measured picosecond time-resolved fluorescence decay profiles were analyzed using the numerical solution of the Debye-Smoluchowski equation with coupled reversible and irreversible proton back-recombination reactions at the source. A full kinetic analysis shows that both the reversible geminate recombination reaction, which assumes at long times a t -3/2 dependence, and the irreversible geminate quenching reaction, which assumes at long times a t -1/2 dependence, are significant in determining the excited-state kinetics of 1-naphthol. |
