Abstract: | Spectrophotometric scans of Mars and the Moon in the region 4000–5000 Å were obtained and ratioed. No evidence of any absorption greater than 3% is visible in the Martian spectrum. Using our own laboratory spectra of NO2 as well as the published work of Hall and Blacet (1952) we confirm Marshall's (1964) upper limit of 8 μm atmospheres (0.0008 cm amagat) for the abundance of NO2 in the atmosphere of Mars. |
