Recent advances in prethermal chemistry: real-time probing of elementary electron transfer reactions

Yann Gauduel

Résumé

In liquids and electrolyte solutions, elementary radical reactions may be investigated on the time scale of molecular motions by femtosecond visible-IR absorption spectroscopy. Some studies devoted to the microscopic understanding of sub-picosecond prehydration electron transfer between an aqueous halide ion (Cl-) and ionic acceptors (Cd++, H+) are presented. Within an electron hydration regime, the one-electron reduction of a metallic ion or a hydrated proton (hydronium or dihydronium ion) is totally achieved in less than 2 × 10^-12 s at 294 K. The consequences of an early partition between reactive and nonreactive IR electronic pathways on the electron hydration process are discussed.
