A Mass Spectrometric Study of the Vaporization of Cuprous Iodide

摘要

The vaporization of CuI was studied using Knudsen effusion-mass spectrometric techniques. The ionic species in the mass spectrum were identified and assigned to the appropriate parent molecules in the equilibrium vapor. Partial pressures for each of the components of the equilibrium vapor were determined as a function of temperature. Second law heats of sublimation were determined and two structural transformations occurring in the solid were characterized. The possibility of a temperature dependent ionization cross section for some of the species is discussed. (Author)
