Photochemistry of aqueous

Visible and UV spectrophotometric techniques are most convenient for studying the polymer and various oxidation states of plutonium. The spectra of the plutonium states and the procedure for resolution of the concentrations were previously described (9 ). Changes in the relative concentrations of the oxidation states and of the polymer generally are determined from corresponding changes in the spectra and a comparison of the changes to standard spectra of the various states. These techniques have been used exclusively for studying the photochemistry of aqueous plutonium.

The photochemistry of aqueous 2-iodophenol was the subject of a subsequent study [19]. Although ring contraction, carbene formation and photohydrolysis took place in this case too, they all were minor pathways (

radical anions. It was concluded that the heterolytic dehalogenation mechanism observed for aqueous 2-chloro- and 2-bromophenol is overruled in the case of 2-iodophenol by a homolytic one promoted by the comparatively weaker carbon-halogen bond [19].

A time-resolved study of the photochemistry of aqueous 2-(3-benzoyIphenyl)-propionic acid reveals that the main pathway for decarboxylation is intramolecular electron transfer through triplet biradicals, and similar examination of the photoreactions of 6H-purine-6-thione (29) shows that ( 29 ) acts as an electron acceptor for tetramethylbenzidine and as an electron donor for />-dinitroben-zene.
