Infrared absorption cross sections for N2O5

Abstract Laboratory measurements of absolute infrared absorption cross sections for three strong bands of N 2 O 5 have been made as a function of temperature from 233 to 350 K. The results of this study confirm most of the recent laboratory studies, indicating reasonable confidence in cross sections for this molecule which are of potential use in its identification and measurement in the atmosphere and in laboratory systems. Beer-Lambert linearity is confirmed and the effect of instrumental resolution on integrated intensities as well as peak cross sections is reported.
