✦ Synopsis

A dissociation process of p-naphtha1 in the excited state has been investigated by measuring the fluorescence decay and the time-resolved spectra. A significant isotope effect on the rate of dissociation has been observed, and the activation energies for the proton transfer are determined. The experimental results suggest that a tunnelling mechanism may be involved in the proton transfer in the excited state.

The static and transient fluorescence spectroscopy of 3-hydroxyflavone, 3HF, has been investigated as a function of deuteration of the 3-hydroxy group and the solvent. Small H/D isotope effects are observed for at least two of the simple rate constants for the excited-state dynamics. The isotope eff
