Laser-Induced Fluorescence Studies of Molecular Dynamics

The vibronic rovibronic fluoresence excitation spectra of biacetyl, methylglyoxal, and pentanedione have been recorded for the excited singlet state of each molecule. In particular, the fluorescence of biacetyl in a molecular beam has been shown to exhibit the quantum beat effect in the time-resolved fluoresence. By the use of a simple, perturbation theory-derived analysis and also a more complicated, simulation-based method, the effective densities of the triplet states involved in the beat phenomena and the mean interaction energies for singlet-triplet state coupling have been determined.
