Abstract

The excited singlet-state and triplet-state properties of C₆₀ in toluene have been measured by picosecond and nanosecond laser-flash photolysis. S₁ has absorption maxima at 513, 759 and 885 nm with differential molar extinction coefficients (Δε{lunate}_S) of 4500, 3700 and 6300 M^-1 cm^-1, respectively. T₁ has absorption maxima at 457, 509 and 747 nm with Φ_TΔε{lunate}_T=3400, 3000 and 15000 M^-1 cm^-1, respectively. The lifetime of S₁ is 1.2 × 10^-9 s and that of T₁ is ≥ 2.8 × 10^-4s. T₁ also undergoes triplet-triplet annihilation with a rate constant ≥ 4.8 × 10⁹ M^-1s^-1.
