Ganske, H.N. Berko, B.J. Finlayson-Pitts Title: Absorption Cross Sections for Gaseous ClNO2 and Cl2 at 298 K: Potential Organic Oxidant Source in the Marine Troposphere Journal/Source: J. Geophys. Res., 97, 7651-7656, (1992); DOI: 10.1029/92JD00414 Data: table, diagram Energy/Wavelength range: 200 - 370 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The absorption cross sections for gaseous ClNO2 in the 200-370 nm region and for Cl2 in the 270-400 nm region have been determined at 298 K. At lambda < 300 nm the absorption cross sections for ClNO2 are in good agreement with those of lilies and Takacs (1976/1977) and Nelson and Johnston (1981) but are higher than those of Martin and Gareis (1956) from 220 to 240 nm. In the tropospherically important region beyond 290 nm our results, which have been corrected for impurity Cl2 using a combination of mass spectrometry and UV absorption, fall between those of Martin and Gareis (1956) and lilies and Takacs (1976/1977) and are in excellent agreement with the values of Nelson and Johnston (1981).
