Over the time scale 10<sup>−8</sup>−10 s, only a few kinetic steps have been observed which have been identified through spectroscopic and kinetic analysis. The reaction rate of e<sup>-</sup><sub>aq</sub> with Ag<sup>+</sup> is lowered in the presence of PA (3.6×10<sup>9</sup>lmol<sup>−1</sup>s<sup>−1</sup> when [PA]/[Ag<sup>+</sup>]=100). The first products (Ag<sup>0</sup> λ<sub>max</sub>≈360 nm, Ag<sup>+</sup><sub>2</sub> λ<sub>max</sub>=310 nm) are similar to those obtained in the absence of PA, except for an additional absorption band (350–450 nm) which indicates that Ag<sup>+</sup><sub>2</sub> is itself complexed. Then through dimerization (2k=3×10<sup>9</sup>lmol<sup>−1</sup>s<sup>−1</sup>) and reaction with the alcoholic radical (in the presence of 2-PrOH, 1.5×10<sup>9</sup>lmol<sup>−1</sup>s<sup>−1</sup>), Ag<sup>+</sup><sub>2</sub> leads to an “Ag<sub>2</sub>” species peaking at 300, 320 and 360 nm, noticeably different from the reported Ag<sup>2+</sup><sub>4</sub> species. Two further steps are observed which are assigned to a ligand reorganization of “Ag<sub>2</sub>” in the millisecond range (10<sup>3</sup><em>s</em><sup>−1</sup>), followed by a coalescence to “Ag<sub>4</sub>” in the range of seconds (10<sup>5</sup>lmol<sup>−1</sup>s<sup>−1</sup>). This last product is thought to be the stable Ag<sub>a</sub> cluster known to be formed by γ-radiolysis. A kinetic simulation accounts for the whole mechanism which is much lower than in the absence of PA.</p></div>","PeriodicalId":14262,"journal":{"name":"International Journal of Radiation Applications and Instrumentation.

Liquid <em>n</em>-hexadecane has been selected as the model linear amorphous polymer and the protection effect has been studied by analyzing the radiolysis products. In the presence of additives, degradation of <em>n</em>-hexadecane, reduction of radiolysis products, including H<sub>2</sub> evolution, and selective degradation of the additive have been observed. Energy transfer (excitation and charge) to the additive reduces the solvent excitation which is the precursor of the radiolysis products. The additive reacts with the solvent molecules according to its reactivity to form adduct compounds. Mass analysis shows that these adduct compounds have a smaller number of double bonds in their aromatic rings due to hydrogenation. Aromatic compounds are more reactive than hydroaromatic compounds towards <em>n</em>-hexadecane and their adducts consume more hydrogen than those of the hydroaromatic compounds, and therefore aromatic compounds reduce gas formation more effectively than hydroaromatic compounds. From the effect of aromatic compounds, it is concluded that hexadecene is produced neither by H<sub>2</sub> elimination from the lowest excited state of <em>n</em>-hexadecane nor by disproportionation of <em>n</em>-hexadecyl radicals, but is mainly produced directly from the decomposition of the excited cations of <em>n</em>-hexadecane.</p></div>","PeriodicalId":14262,"journal":{"name":"International Journal of Radiation Applications and Instrumentation.
