The absorption spectra, the fluorescence excitation spectra and the relative fluorescence quantum yields of trans-stilbene in planar supersonic jets were determined for excess vibrational energies EV = 0-5000 cm-1 above the origin of S1. The non-radiative decay rates reveal an onset at EV ≈ 900 cm-1, exhibit the erosion of vibrational photoselectivity for isomerization at EV = 900-5000 cm-1 and show a linear dependence on EV for EV = 1500-5000 cm-1.
