Negative ion photoelectron spectroscopy of solvated electron cluster anions, (H2O)− n and (NH3)− n

Reactions of Hydrated Electrons (H2O)n− with Carbon Dioxide and Molecular Oxygen: Hydration of the CO2− and O2− Ions

“…[23,24] Hydrated electrons in the gas phase, (H 2 O) n À , were first reported by Haberland and co-workers, [25][26][27] and extensively characterized spectroscopically, among others by Bowen and co-workers. [28][29][30] A series of experiments by the groups of Johnson and Viggiano [31,32] in molecular beam and flow reactor set-ups has revealed an interesting variety in their behavior towards different gaseous reactants. As typical electron scavengers, diatomic O 2 , as well as the usually extremely stable and unreactive CO 2 molecules, are "dissolved" in the (H 2 O) n À with high efficiency.…”

“…We have reported preliminary calculations for two book-type structures of I À (H 2 O) 6 cluster. In this paper, we report full accounts of our previous work and present direct dynamics simulations for the I À (H 2 O) 4 , I À (H 2 O) 5 and I À (H 2 O) 6 clusters.…”

“…Understanding of early stage dynamics of such processes has been an important issue in various fields including chemistry, physics and biology. Although electron solvation phenomena are intrinsically condensed phase ones, previous experimental studies clearly show that molecular clusters are quite useful for understanding the structure, dynamics and reactivity of solvated electrons from a microscopic point of view [4][5][6][7][8]. This is because clusters can easily be generated under gas phase conditions and then various sophisticated spectroscopic and timeresolved techniques can be applied to such clusters.…”

Clusters: A bridge between disciplines

“…The electronic, optical, and magnetic properties of mass isolated clusters are studied by using a number of experimental techniques, including resonant ionization and electric and magnetic deflection methods. The ionization potential, electron affinity, dissociation energies, gap between highest occupied molecular orbitals (HOMO) and lowest unoccupied molecular orbitals (LUMO), and reactivity provide a wealth of information that can be used to characterize a cluster and study the evolution of its properties with size and composition; here, photoelectron spectroscopy is frequently the method of choice (20)(21)(22)(23).…”
