Abstract

High-resolution vacuum ultraviolet photoabsorption cross sections of CO2 are required for accurate modeling of airglow emissions from the Martian and Venusian atmospheres and for photochemical models of those and Earth's atmospheres. We report cross section measurements between 91,000 and 115,000cm-1 (87-110nm) at spectral resolutions of 1.15cm-1 (91,000-102,000cm-1) and 0.58cm-1 (102,000-115,000cm-1). These high-resolution cross sections show significant deviations from the results of previous lower-resolution measurements, particularly in regions with sharp spectral structure.
