Kurylo, T.J. Wallington, P.A. Ouellette Title: Measurements of the UV absorption cross-sections for HO2 and CH3O2 in the gas phase Journal/Source: J. Photochemistry, 39, 201-215, (1987); http://dx.doi.org/10.1016/0047-2670(87)80032-1 Data: table, diagram Energy/Wavelength range: 210 - 250 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: Relative values of the gas phase absorption cross-sections s for hydroperoxy (HO2) and methylperoxy (CH3 O2) radicals were determined at 298 K over the wavelength lambda ranges 210 - 250 nm and 210 - 280 nm respectively.
