Talukdar, J.B. Burkholder, A.-M. Schmoltner, J.M. Roberts, R.R. Wilson, A.R. Ravishankara Title: Investigation of the Loss Processes for Peroxyacetyl Nitrate in the Atmosphere: UV Photolysis and Reaction with OH Journal/Source: J. Geophys. Res., 100, 14163-14173, (1995); DOI: 10.1029/95JD00545 Data: table, diagram Energy/Wavelength range: 220 - 325 nm Resolution: Temperature: 250 K; 273 K; 298 K Temperature dependence: yes Pressure/Concentration: Phase: gas pH: Comments: The UV absorption cross sections of peroxyacetyl nitrate (PAN), CH3C(O)O2NO2, have been measured as a function of temperature (298,273, and 250 K) between 195 and 345 nm using a diode array spectrometer. The absorption cross sections decrease monotonically with increasing wavelength. The cross sections also decrease as the temperature is lowered.
