 Title    Could Hydrogen Peroxide Photolysis Occur in the Absence of Transition Metals ?  
 Abstract    Quantum yields of hydrogen peroxide photo-lysis increase with the square root of concentra-tion of added Cu(II). The cupric ions are photo-catalytically active already at trace concentra-tions (10~ 7 M), i.e., at the concentrations present in any real reaction system. Hydrogen peroxide photolysis is completely suppressed on addition of complexing agents such as EDTA. It is believed that no hydrogen peroxide photolysis would occur in complete absence of photo-catalytically active transition metal ions.

 Title    Oxidation of Tetraline by Dioxygen. Effect of Fe(acac)3 on the Thermal and Photoinitiated Reactions  
 Abstract    The photochemical oxidation of tetraline by dioxygen is catalyzed by ferric acetylacetonate (iron(III) 2,4-pentadionate), the reaction rate increasing markedly with temperature. The rate-determining step of the photochemical oxidation is presumably a catalyzed thermal reaction.
