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: table, diagram Energy/Wavelength range: 240 - 750 nm Resolution: Averaged over 5nm intervals Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: vapor pH: Comments: The spectrum shows four absorption bands with maxima at 314 nm [sigma=(2.1+-0.3)x10-18 cm2 molecule-1], 350 nm [sigma=(1.9+-0.2)x10-18 cm2 molecule-1], 520 nm [sigma=(4.4+-0.5)x10-20 cm2 molecule-1], and 665 nm [sigma=(6.2+-0.9)x10-20 cm2 molecule-1].
