N2 - We report measurements of single vibronic level fluorescence spectra of benzene cooled in a supersonic expansion. The levels for which spectra have been recorded are O0, 11, 61, 6111, 6112, and 6113. The spectra reveal Fermi resonance in both the excited and ground electronic states. The analysis of these resonances is reported, in particular the 6111-81 resonance which permeates the spectra. From the analysis some ground state anharmonicity constants involving v8 have been determined. High resolution scans of the transitions provide upper bounds to the rates for intramolecular vibrational energy redistribution (IVR) from S0 levels up to ∼ 9200 cm-1.
