Electronic Structure Predictions of the Energetic Properties of Tellurium Fluorides

“…As another test, we calculated the BDE of 3 TeO (Table 1), which is not as well established as that of 3 Te 2 . 80,81,83 The spin−orbit corrections to the dissociation energy obtained as described above are −5.27 kcal/mol and −4.95 kcal/mol for the experimentally derived (one-half of 679 cm −1 ) 83 and 4c-KRCI values, respectively.…”

“…Tellurium has 38 isotopes and 17 nuclear isomers with atomic masses from 105 to 142; there are 8 naturally occurring isotopes. Tellurium is a fission product in nuclear reactor fuels (a radioactive decay product of uranium and its daughters, as well as from other nuclei) and will thus be formed in molten salt reactors. − Tellurium can lead to the embrittlement of nickel-based structural materials such as the Ni–Mo alloy Hastelloy-N at the surface grain boundaries. , Thus, it is important to know the thermodynamic properties of the tellurium fluorides as the fluoride anion is often the anion of use in molten salt reactors. The properties, especially the vibrational spectra, of TeF 6 have received significant attention. − The structure of TeF 6 has been obtained from a temperature dependent electron diffraction study and in the solid state by X-ray diffraction .…”
