Unimolecular reactions in isolated and collisional systems: is the transition-state rate an upper limit for the isomerization of stilbene?
1986
The Journal of Physical Chemistry
The effect of few-body (e.g., binary) collisions on photochemical trans-cis-stilbene isomerization was studied by measuring the transient fluorescence decay from isolated-molecule conditions up to 5 atm of methane gas pressure at room temperature. Simple statistical considerations were found to account for the thermal isolated-molecule decay using as a basis the energy-dependent rates k(Ex) measured in supersonic jet experiments. The isomerization rate was found to increase with methane
