Substance: HOBr Orlando, J.J., and J.B. Burkholder Gas Phase UV/Visible Absorption Spectra of HOBr and Br2O J. Phys. Chem., 99 (1994), 1143-1150. Data: table Resolution: 2.0 nm Temperature: 298. K Temperature dependence: no Comments: HOBr was prepared by reaction of Br2O with H2O. Br2O was synthesized via rection of Br2 with HgO. Br2O could not be obtained free of Br2 contamination.
