The gas-phase infrared spectrum of OBrO has been measured for the first time. The ν1 and ν3 symmetric and asymmetric stretching vibrations of bromine dioxide have been measured at high resolution using the White cell at the beamline for infrared spectroscopy at MAX-Lab. In addition, the ν1 + ν2 transition is observed. Interest in halogen oxides has been stimulated by their role as catalysts in stratospheric ozone depletion. A great deal of effort has gone into understanding the mechanisms of ozone depletion processes which involve chlorine. There is evidence from direct observation of earth's atmosphere that bromine species are also involved. Unfortunately, due to the difficulty of their synthesis and the limitations of instrumentation there are few laboratory studies concerning the structure and reactivity of the members of the BrO x family.
