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.
