IR absorption spectra of the vapors over indium and thallium metaborates

Thermodynamic properties and structure of gaseous metaborates

“…These frequencies have been calculated using the ionic model from the known salt structure. According to [80,81], the vibrational frequencies of the metal-oxygen bonds are equal Frequency [50], Ar [85], Ar, Kr [49], gas [84], gas [51], Ar, Xe [86][87][88][89], the conclusion was drawn that not only InBO 2 and TlBO 2 metaborates but also all oxygen-containing acid salts of Group I and III elements have a ring structure (Fig. 1c).…”

“…The absence of this structure and intermolecular interactions is responsible for the observation of very narrow bands of the dissolved molecules in the spectrum and the possibility of resolving even closely spaced peaks of metal isotopes. The IR spectra of alkali metaborate molecules in the gaseous phase and those isolated in noble-gas matrices were investigated in [49][50][51][83][84][85]. The frequencies of normal vibrations were determined, and the inferences regarding planar angular geometric configura- -47] tions of these molecules were made in these works.…”

Mass Spectrometric Study of Stability, Thermochemistry and Structures of the Gaseous Oxyacid Salts

“…Furthermore, these spectra are difficult to interpret, as the role of rotational and vibrational "hot" bands grows. At present the high-temperature IR spectra of the metaborates of alkali metals [130][131][132][133][134] and indium and thallium [135], cesium nitrite, cesium and thallium nitrates [134], as well as gallium, indium, and thallium molybdates [135] have been reported. The matrix isolation method is successfully applied for studying stable salts in vapor [59].…”
