Abstract
ELECTRON-TRANSFER reactions with europium (II) as the reducing ion have been studied in aqueous perchloric acid solution, μ = 2.0 M, using conventional spectrophotometric techniques. Such reactions are of interest in that little is known about the readiness with which electrons are transferred to and from f-orbitals1,2. Although europium (II) is the most stable of lanthanide (II) oxidation states, it reacts rapidly with oxygen and oxygen-free systems have therefore to be used. In preliminary experiments it was shown that europium (II) reduction of perchlorate ions is negligible (europium (II) concentrations of the order 0.04 M).
