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.
