Radiation stability of fullerenes: pulse radiolysis of C60 and C70 in hydrocarbon solvents

Abstract

The transient optical absorption spectra obtained on electron pulse radiolysis of de-aerated solutions of C₆₀ and C₇₀ in benzene have been assigned to the triplet states with G(^TC₆₀)= 0.52 and G(^TC₇₀)= 0.48. Low G(–C₆₀) and G(–C₇₀) in the steady-state γ-radiolysis in benzene and hexane suggest their stability towards γ-radiation.
