Oxidation state and chemical shift investigation in ...

Assuming the algebraic sum of oxidation states of all atoms in a neutral molecule/unit-cell must be zero, together with the fact that some elements almost always have certain oxidation states (due to their very high electropositivity or electronegativity, e.g., K + and O 2−), the formal oxidation state of the remaining atom (such as TMs) can be calculated in simple compounds.

Investigation of the titanium oxidation states by Auger ...

The different stages of the oxidation procedure of polycrystalline titanium have been investigated by Auger electron spectroscopy. The oxidation was carried out under distinct oxygen partial pressures in the range of 5 × 10 -8 -5 × 10 -5 Torr at room temperature. The identification of the formed titanium oxides was based on the line shape analysis of Ti LMM peaks and on the quantification of ...

Oxidation States of Copper Ions in ZSM-5 Zeolites. A ...

The redox behavior of Cu/ZSM-5 zeolites prepared by ion exchange from Cu2+ aqueous solutions has been followed by a variety of spectroscopic techniques to provide a thorough picture of the so-called “self-reduction” of cupric ions, which occurs upon dehydration of the hydrated system at various temperatures, and of the reverse process of reoxidation as well. Conflicting hypotheses on both ...

How Far Can We Go? Quantum‐Chemical Investigations of ...

The highest known oxidation state of any element is +VIII. After the recent discovery of Ir VIII O 4 under cryogenic conditions, we have investigated the stability of cationic species [MO 4] + (M=Rh,Ir,Mt). Such compounds would formally represent the new oxidation state +IX, which is experimentally unknown so far for the whole periodic table.

Abstract. Compounds of antimony normally contain the element In either the III or the V oxidation state. Compounds containing these oxidation states give rise to 121 Sb Mössbauer spectra yielding parameters which fall within reasonably well defined limits for each oxidation state. It has been clearly demonstrated by Stevens and Bowen at a previous Symposium 1 that antimony in the III ...
