Abstract

\begin{wrapfigure}{c}{0pt} \includegraphics[scale=0.65]{3.eps} \end{wrapfigure} Electron transfer reactions are among the most elementary chemical reactions, which play a fundamental role in organic synthesis, electrochemical processes, and biochemical reactions. In our study, we used sodium as a source of electrons and probed the formation of benzophenone radical anion \textbf{2} in an argon and low density amorphous (LDA) water ice matrices using matrix isolation technique. \vspace{0.25em} In solid argon, mixture of sodium vapors and benzophenone \textbf{1} was co-deposited and after irradiating the matrix with the visible light, electron transfer takes place from sodium to \textbf{1} under the formation of radical anion \textbf{2}. In LDA water ice, hydrated electrons are produced after co-deposition of water with sodium. The hydrated electrons react with benzophenone without photochemical activation and resulted in radical anion \textbf{2}. However, the photoexcitation of radical anion \textbf{2} yielded back benzophenone \textbf{1} after losing an electron to the matrix.\textsuperscript{{[}1{]}} \vspace{0.5em} \textbf{Reference:} {[}1{]} A.
