Dispersed fluorescence spectra following the excitation of the CBr 2 Ã 1B1X̃ 1A1 2013 and 2014 bands at visible wavelengths were acquired in a discharge supersonic free jet expansion using an intensified charge-coupled device (ICCD) detector. The dispersed fluorescence spectra show signal-to-noise ratios of up to 60 and extend out to a maximum red shift frequency of 6000 cm-1. Complete and detailed vibrational structure of the ground singlet state (X̃ 1A1) was observed. Vibrational parameters including fundamental frequencies, anharmonicities, and coupling constants were determined for the CBr2 X̃ 1A1 state. Additional vibrational structure starting at approximately 3650 cm-1 was observed and this indicates the singlet-triplet energy gap to be > 10 kcal mol-1.
