The fluorescence and fluorescence-excitation spectra of C{sub 60} in a hydrocarbon glass at 1.2 K are reported. The fluorescence spectrum resembles that of a molecular X-trap in crystalline C{sub 60}. The vibronic bands in these spectra are assigned, and the intensity distribution among the false origins points to vibronic coupling within the singlet manifold. The lowest excited singlet state of C{sub 60} shows predominantly T{sub ig} and G{sub 2} character. Additionally, we show that a reduction of the symmetry of C{sub 60} by either an intra- or an intermolecular perturbation leads to a fluorescence spectrum with a strong 0-0 transition and a different vibronic structure. 14 refs., 4 figs., 4 tabs.
