Photoelectron spectroscopic characterization of vapors over heated inorganic solids

Most inorganic compounds, particularly the ionic ones, are solids at room temperature. Some of them, when they are heated to produce vapors, maintain their atom-ratio integrities in the gaseous species. Of these, a sizable percentage yield the monomeric vapor species as the predominant constituent of the gaseous phase. It is chiefly this category of compounds that are treated in the present paper, namely, those solid inorganic compounds which when heated produce vapors which are predominantly monomers having the same atom ratios as the solid substances
