✦ Synopsis

We have used a simple Ar+synchronously pumped and cavity-dumped dye-laser system to generate UV picosecond pulses with energies sufficiently high for absorption recovery experiments. With these pulses, we have studied the dynamics of the isomerization of trans-stilbene in n-alcohols as a function of viscosity and temperature. It is concluded that the exited-state barrier of trans4lbene in ~z-alcohols is less than 1 kcal mol-' and that the trans -cis isomerization yield is 0.54 2 0.05.

Time-resolved atomic absorption spectroscopy in the vacuum ultraviolet has been employed to monitor electronically excited oxygen atoms, 0(2\*D2), following their generation by the flash photolysis of ozone in the Hartley band region. We report the first values for the absolute second-order rate con
