Mode-Specific Intramolecular Vibrational Energy Redistribution: Direct Picosecond Measurements


In this Letter, we report on the direct picosecond measurement of mode-dependent, dissipative IVR rates in jet-cooled trans-stilbene. It is found that excitation of different bands in the S_1 + 1250-cm^(-1) energy region of the molecule gives rise to different IVR rates, as determined by the temporal evolution of vibrationally unrelaxed fluorescence. The results are discussed in terms of the spectroscopic assignments for the excitation bands.
