Abstract

Absorption cross-sections for HNO₃ and N₂O₅ have been measured in the wavelength region 220 - 450 nm, using a dual beam diode array spectrometer with a spectral resolution of 0.3 nm. The results for both compounds are in good agreement with recommended values at room temperature. Cross-sections of both HNO₃ and N₂O₅ show a marked reduction with decreasing temperature in the range 295 - 233 K.
