An experimental study of the sublimation of water ice and the release of trapped gasesThe release of the more volatile component of the Ar/H2O, CO/H2O, and CO2/H2O mixtures presently studied during sublimation is found to occur in several discrete temperature regions; gas release correlates with IR spectrum changes of the solid ice. Relative peak intensities during warming are noted to depend on the initial gas/H2O ratio. The irradiation of CO- or CO2-containing ices respectively led to the release of CO2 and CO, as well as the initial species. The implications of these results for cometary behavior are discussed.
