The ESR and the electronic absorption spectrum of the radical anion of C60 produced by electrolysis were measured at room temperatures and at 77 K. A singlet ESR spectrum with g = 1.999 appeared only at 77 K while the electronic absorption spectrum was observed both at room temperatures and at 77 K. The small value of the g factor was associated with the residual orbital angular momentum. The irregular vibrational structure of the electronic absorption of the radical anion in the frozen matrix band was suggested as being due to the Jahn-Teller distortion.
