Abstract
Dinitrogen pentoxide (N2O5) is an important night-time reservoir for NO2 and NO3 in the atmosphere. Toon et al.1 first observed N2O5 in the atmosphere in infrared spectra recorded at sunrise by the Atmospheric Trace Molecule Experiment aboard Spacelab 3. Their results have motivated renewed interest in laboratory investigations of N2O5 to obtain accurate intensity data for modeling the atmospheric spectra2-5. Also, ab initio electronic structural calculations have been undertaken to estimate integrated infrared band intensities to compare with the experimental results6.
