Abstract

The formation of hot trans-stilbene by photoisomerization of cis-stilbene, and its subsequent vibrational cooling, have been monitored by picosecond two-color uv pump-probe anti-Stokes Raman spectroscopy. Hot ground-state trans-stilbene appears promptly within our 10 ps experimental time resolution, and the anti-Stokes intensity decays with a time constant of 39 ± 10 ps in cyclohexane and 17 ± 5 ps in methanol. The decay of the anti-Stokes intensity is accompanied by a shift of the C=C stretching vibrations by about 20 cm−1 to higher frequencies, due probably to cooling of other vibrational modes anharmonically coupled to the C=C stretches.
