Mossbauer spectroscopy terminals

A detailed investigation, involving elastic and inelastic neutron scattering and Mossbauer spectroscopy has been carried out on Nation membranes as a function of water content. Nafion membranes consist of a perfluoroethylene backbone with side chains having a terminal sulphonic acid group. [Pg.210]

When the precursor to the Fe(III,IV) compound is [Fe 2(/r-0)2(6-Me3-TPA)2] +, one-electron oxidation affords a Fe k 0-Fe =0 core structure derived from the isomerization of the Fe2(/r-0)2 diamond core, demonstrating the accessibility of a terminal Fe =0 unit in a nonheme environment. A different approach to achieve the Fe(III,IV) unit has also been carried out by Lippard etal. In this method, a tetracarboxylate-bridged diiron(II,II) complex (4-t-BuPy)2Fe2(/r-RC02)4 where RC02 is the bulky carboxylate Ar C02 (Schemed) is exposed to dioxygen at -79°C. Among the products identified by Mossbauer and EPR spectroscopy is an Fe(III,IV) species. [Pg.2011]
