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.
