Comments: The temperature dependence of the HNO3 absorption cross sections between 240 and 360 K over the wavelength 
range 195 to 350 nm has been measured using a diode array spectrometer. The HNO3 absorption spectrum showed a temperature 
dependence which is weak at short wavelengths but stronger at longer wavelengths
