The electronic absorption spectrum of parafluorobromobenzene is reported together with its band shape and molecular geometry. The electronic transition is found to be the 2900–2400 Å system and the analysis consistent with other paraheterohalogenated benzenes. The intense bands, including 0–0, are double headed and areB-type in nature.A-type vibronic bands are also observed although less intense than theB-type bands. In all 9 excited states and 5 ground state fundamentals could be assigned.
