✦ Synopsis

Pulse radiolysis and laser flash photolysis have been used to determine properties of the lowest triplet state of Cl0 in benzene at room temperature, including its absorption spectrum between 300 and 1620 nm, its molar absorption coefficients (or= 3800 dm' mol-' cm-' at 970 run) and its quantum yield of formation in benzene @+0.76 k 0.15. Measurements were also made of the quantum yield @*=0.82 f0.15 for the Crs sensitised formation of Os('A&. Transition assignments, oscillator strengths, and optical limiting properties of CT0 are discussed.
