摘要：

Pulse radiolysis and laser flash photolysis have been used to determine properties of the lowest triplet state Of C70 in benzene at room temperature, including its absorption spectrum between 300 and 1620 nm, its molar absorption coefficients (epsilon(T)=3800 dm3 mol-1 cm-1 at 970 nm) and its quantum yield of formation in benzene PHI(T) = 0.76+/-0.15. Measurements were also made of the quantum yield PHI(DELTA)=0.82+/-0.15 for the C70 sensitised formation of O2(1DELTA(g)). Transition assignments, oscillator strengths, and optical limiting properties Of C70 are discussed.
