Abstract: The geometry optimization of radical anion C₆₀^- has been performed by INDOseries of method and the D_2h symmetry structure has been obtained. It is illustrated that the JahnTeller distortion has happened for C₆₀^- definitely, inducing the single bonds to be shortened and the double bonds to be lengthened, and l5 kinds of bonds and 9 kinds of different atoms have been formed, whereas the extra negative charge distribute near the equator mostly. On the basis of this geometry, the electronic spectrum of C₆₀^- has been calculated, the result is in good agreement with the experimental one.The spectrum has been assigned theoretically and the reason of red shift has been discussed.

Key words: C₆₀^-(D_2h), Jahn-Teller distortion, Electronic absorbed spectrum
