Kamps, H. Mueller, M. Schmitt, S. Sommer, Z. Wang, K. Kleinermanns Title: Photooxidation of exhaust pollutants: I. Degradation efficiencies, quantum yields and products of benzene photooxidation Journal/Source: Chemosphere, 27 (11), 2127-2142, (1993) Data: table EnergyWavelength range: 185 nm; 254 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: gas pH: Comments: For determination of absorption cross sections a narrow band Hg-low pressure lamp with defined emission bands at 185 nm and 254 nm was used. Benzene as well as acetone show structured absorption spectra in the 254 nm region so that the absorption cross sections depend fundamentally on the spectrometer bandwidth. The absorption cross sections measured with the Hg-lamp were considerably higher than the broadband values in the literature. Author to whom correspondence should be addressed: (e-mail address):
