Rattigan, D.J. Lary, R.L. Jones, R.A. Cox Title: UV-visible absorption cross sections of gaseous Br2O and HOBr Journal/Source: J. Geophys. Res., 101, 23021-23034, (1996); DOI: 10.1029/96JD02017 Data: diagram, table Energy/Wavelength range: 235 - 430 nm Resolution: 0.6 nm (fwhm) Temperature: Temperature dependence: Pressure/Concentration: Phase: gas pH: Comments: The spectrum of HOBr shows two main absorption bands with maxima near 282 nm [sigma=(3.1±0.4)x10-19 cm2 molecule-1 and 350 nm (sigma=12.5±1.6)x10-20 cm2 molecule-1] extending out to 430 nm. In addition we provide evidence in support of a weak band in HOBr around 440 nm (sigma~7.5x10-21 cm2 molecule-1) Author to whom correspondence should be addressed: (e-mail address):
