Abstract
Dilute solutions of Mn3+ ions in pure MgO are ESR silent, but on reduction by spiltover hydrogen from noble metals show strong ESR signals characteris tic of Mn2+ ions in this matrix. The same solids are also active for the de hydrodimerization of triphenylamine at room temperature as shown by the pre sence of both radical cations and Mn2+ ions. (C) 2000 Elsevier Science B.V.
