Vaghjiani, A.R. Ravishankara Title: Absorption cross sections of CH3OOH, H2O2, and D2O2 vapors between 210 and 365 nm at 297 K Journal/Source: J. Geophys. Res., 94, D3, 3487-3492, (1989); DOI: 10.1029/JD094iD03p03487 Data: table, diagram Energy/Wavelength range: 210 - 365 nm Resolution: Temperature: 297 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The gas phase absolute UV absorption cross section at 213.9 nm for CH3OOH, H2O2, and D2O2 have been determined to be (22.51±0.78)× 10-20, (33.04±2.17)×10-20, and (35.37±4.25)×1020 cm2 molecule-1, respectively, at 297±1 K. The corresponding values at 253.7 nm for H2O2 and D2O2 were (7.37±0.31)×10-20 and (7.86±1.04)×10-20 cm2 molecule-1. The absorption spectra of these peroxides were recorded in the wavelength region between 210 and 365 nm. Author to whom correspondence should be addressed: (e-mail address):
