AbstractBased on the Bogoliubov-de Gennes formalism, the linear multi-mode T-1u circle times 8h(g) static Jahn-Teller problem is aanalyzed for the charged C-60(-), C-60(2-), the lowest triplet and singlet self-trapped exciton (STE) of C-60. The dynamic Jahn-Teller effect due to quantum tunneling between the six degenerate D-5d configurations is studied within a perturbation approach. The tunneling induced level splittings are determined to be T-2(1u) circle plus T-2(3u), (1)A(g) circle plus H-1(g), T-3(3g) circle plus T-3(1g) and T-1(3g) circle plus T-1(1g) for C-60(1-), C-60(2-), triplet and singlet STE's of neutral C-60, respectively. The observable consequences of the dynamic Jahn-Teller effect are considered. Some of the Jahn-Teller active (as well as Raman-active) modes are predicted to be observable as multi-phonon overtones in the infrared absorption. In the photo-induced multi-phonon resonant Raman scattering the tunnel splitting itself should show up in the Raman spectrum, and the depolarization ratio is sensitive to the exciting frequency.
