Abstract
µs and ns excitation of aqueous solution of uranyl salts produces a short-lived absorption (t½ca. 1·05 µs) which is systematically quenched on addition of a variety of organic substrates known to photoreduce UO2+ 2 ion; the isotope effect of 2·76 obtained with CH3OH and CD3OH exactly matches that found for quenching of the fluorescence of UO2+ 2 by these substrates, and absolute rate constants have been determined for some photoreactions of UO2+ 2 for the first time.Keywords
