Abstract: Vibrational data, for several common metal-oxyanion ion pairs $(M{^{+}}ClO_{3}{^{-}}, M{^{+}}NO_{3}{^{-}}, M^{+}C1O_{4}{^{-}})$, isolated from the vapor phase in both inert and associating matrices, have become available in recent years. The alkali metal and thallium sulfates are also volatile, but require significantly higher temperatures for vaporization. ($\sim$ $1100^\circ K$), which complicates the matrix isolation studies. Data have now been obtained for the alkali metal sulfate ion triplets, isolated in argon and xenon matrices, after a study of the glassy deposits of the sulfate vapors in an effort to adjust vaporization conditions to minimize salt decomposition to $SO_{2}, \ M_{2}O$ etc., as well as to obtain the infrared spectra of the pure glassy metal sulfates. Based on the magnitude and extent of splitting of the sulfate triply degenerate modes the ion-triplet spectra are consistent with a $D_{2d}$ bidentate structure.
