UV absorption cross-sections for N2O5 were measured in the wavelength
region 240-420 nm and in the temperature range 313-233 K, using a dual
-beam diode array spectrometer. Assessment of the concentrations of im
purities in the N2O5 samples required measurement of the IR spectra fo
r N2O5 and HNO3. Therefore, absolute IR band strengths for the HNO3 13
80-1280 cm-1 and 930-840 cm-1 bands and the N2O5 1280-1210 cm-1 and 78
0-710 cm-1 bands were also measured. The results of both absorption cr
oss-sections and band strengths are in excellent agreement with previo
us studies.
