Paper Abstract

The nature of the optical excitations at the dipole forbidden optical gap of crystalline C60 is investigated by linear and non-linear spectroscopic techniques. The resonances observed both in the absorption and emission spectra are identified with Herzberg-Teller vibronic coupling of the electronic states to intramolecular vibrational modes. The highly structured fluorescence spectra of both C60 single crystals and crystalline C60 films are interpreted in terms of Frenkel exciton emission from X-traps.
