Abstract

Using diffuse reflectance laser flash photolysis, the lifetimes of the triplet states of valerophenone and diphenylbutyrophenone adsorbed on solid silica have been determined to be 0.3 and 0.9 μs respectively. These lifetimes are at least two orders of magnitude greater than those found in homogeneous solution. Quenching of the triplet states by gas-phase oxygen and butadiene is observed.
