Abstract : Coulomb coupling between the two holes in the fullerene cation C60 2+ results in high- and low-spin terms. Vibronic coupling of the high-spin terms to a single mode of vibration of hg symmetry can distort the lowest adiabatic potential-energy surface into wells of D3d, D5d, D2h, or C2h symmetry depending upon the precise nature of the coupling produced by different admixtures of the two sets of coupling coefficients arising from the two H -type irreducible representations appearing in the symmetric part of the H H Kronecker product. The symmetry of dynamic distortions of C60 2+ ions when coupling to all eight of the possible hg modes is taken into account depends very closely on both the vibronic coupling parameters and the splittings between different Coulomb terms. Using estimates for these parameters from the literature leads us to conclude that the distortional symmetry is most likely to be D2h, but there is also the possibility that it could be D3d.
