Theoretical calculation of pseudorotation rates applicable to the C60- ion

The dynamical nature of the Jahn-Teller effect in the T circle times h Jahn-Teller system is explored theoretically using the time-evolution operator to obtain analytical expressions for the rate of pseudorotation between equivalent potential wells in the adiabatic potential energy surface as a function of the vibronic coupling parameters. We outline experiments that should be capable of measuring the pseudorotation rate in the C-60(-) ion, and other systems derived from C-60. The theory presented here could then be combined with such data to probe the nature of the vibronic coupling in these fullerene systems.
