Dipole moment effects in photodetachment from cluster anions
… major advantage of using solvated atomic iodide anions: I<super>−</super>·(Y)<sub><italic>n</italic></sub>: Y = solvent molecule, <italic>n</italic>=1 to 3)) to study this effect is that in the ground state, the excess electron is mainly localized on the iodine atom for which …

Photoelectron Imaging of Iodide Centered Alkyl Halide Cluster Anions
<p>This dissertation presents results from cluster anion photodetachment experiments of the solvated iodide anion as a means of investigating electron molecule interaction. Due to the localization of the excess charge on the iodine atom, these experiments proceed analogously to electron scattering …

Photoinitiated Dynamics of Cluster Anions via Photoelectron Imaging and Photofragment Mass Spectrometry
Mass-selected cluster anions are employed as model micro-solutions to study solvent effects on the structural motifs and electronic structure of anionic solutes, including the roles of the solvent in controlling the outcomes of photochemical processes. Interaction of light with cluster anions can …

Dissociation, relaxation, and oxidation of highly vibrationally excited gas phase metal carbonyl and cluster anions.
… in highly vibrationally excited metal-containing anions. The low-pressure environment of the FT-ICR trapping cell is optimal for the intentional study of nonthermal species. Vibrationally excited anions were prepared with well-defined excess internal energies by the absorption of a single 1064 nm …

Functional polyoxometalate assemblies: from host-guest complexes to porous frameworks
… chemistry of two sets of isopolyoxometalate clusters is investigated. In particular the binding modes of cationic alkali and alkali earth metals through coordinative interactions with the cluster anions {Mo36} and {W36} were compared and contrasted. It was shown that the ionic radii of the …

INDUCING ACTIVE SITES IN CLUSTERS: REACTIVITY OF Al13Ix- and Al14Iy- (x=0-2, y=2-4) WITH METHANOL
… reactivity has been observed in pure aluminum cluster anions as a result of Lewis acid and base pairs. Using this a starting point, the goal of this study has been to explore how reactivity is affected with the addition of one or more ligand, which may induce active sites on the surface of the …

Gas-Phase Covalent And Non-Covalent Ion/ion Chemistry Of Biological Macromolecules
… on peptide and protein cations via Schiff base cluster anions. This dissertation also highlights the gas-phase transformation of phosphatidylcholine cations into demethylated phosphatidylcholine anions, which provides an increase in structural information upon activation. As a whole, gas-phase …

Ionic conductivity transitions in antiperovskite ionic conductors
… atom substitution and the incorporation of cluster ions. Moreover, some AP compounds exhibit non-linearity in the Arrhenius plot of ionic conductivity. At higher temperatures, ion conductivity of AP materials curve upward, while most of the known solid electrolytes exhibit negative …

Methyl Halide Cluster Anion Photoelectron Spectra and Angular Distributions as a Probe of Electron-Molecule Interactions
… electron &ndash molecule interactions using cluster anion photodetachment. Photodetachment from an atomic centered cluster anion produces a free electron and a residual neutral species at a geometry near that of the unperturbed neutral ground state. Evidence of the free electron &ndash …
