Thermochemistry of Atmospheric Metal Reactions

Abstract

As part of a research program carried out during the period May, 1990 through September 1991, we have used effusion-beam mass spectrometry to study the thermochemistry and related aspects of several chemical systems pertinent to the understanding of some atmospheric metal reactions. First, the Na2O-CO2-H2O system was examined for evidence of gaseous NaHCO3 or other carbonates that may be important as sinks for sodium in the atmosphere. Second, the mass spectrum and ionization efficiency curves of Na2O vapor were studied to obtain information about the thermodynamic stability-of the superoxide NaO2. And thirdly, the thermochemical properties of the gaseous oxides OsO2 and OsO were determined to supplement earlier work on OsO3 . The results are summarized in three journal preprints.
