Morel, R. Simonaitis J. Heicklen Title: Ultraviolet absorption spectra of HO2NO2, CCl3O2NO2, CCl2FO2NO2 and CH3O2NO2 Journal/Source: Chem. Phys. Let., 73, 38-42, (1980); http://dx.doi.org/10.1016/0009-2614(80)85197-9 Data: table, diagram Energy/Wavelength range: 200 - 290 nm Resolution: Temperature: 296 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The ultraviolet absorption spectra of HO2NO2, CCl3O2NO2, CCl2FO2NO2, and CH3O2NO2 were measured from 210 to 280 nm. The spectra are similar, and the absorption intensity increases as the wavelength decreases with a shoulder at ~ 255 nm. Author to whom correspondence should be addressed: (e-mail address):
