Abstract
The effect of low concentrations of nitric oxide on the hydrogenatom initiated decompositton of monogermane at room temperature has been studied by a mass-spcctrometrtc technique. Initiation by hydrogen atoms, formed by mercury photosensitization of hydrogen-rich mixtures, insure the primayy decomposition path to be one forming germyl free radicals. The nitric oxide reacts efficienlly with germyl radicals thereby completely suppressing the normal formation of digermane until the nitric oxide concentration has been greatly reduced. The producss of the suppressonn reaction are digermylether (digermoxane), nitrous oxide, nitrogen and a solid containing germanium, hydrogen and oxygen. A mechanssm to account for these experimental facts is proposed and some of the rate constanss of the elementary chemical reactions have been estimaeed.
