ABSTRACT Photoelectron spectra of two species, Al3O3(H2O)2- and Al3O3(CH3OH)2-, that are produced by the addition of two water or methanol molecules to Al3O3- are interpreted with density-functional geometry optimizations and electron propagator calculations of vertical electron detachment energies. In both cases, there is only one isomer that is responsible for the observed spectral features. A high barrier to the addition of a second molecule may impede the formation of Al3O3N2H6- clusters in an analogous experiment with NH3.

    ABSTRACT: The chemical reactions of water, methanol, and ammonia with Al5O4- have been studied using electronic structure calculations. The chemistry of Al5O4- with these molecules is different from that of Al3O3-. While Al3O3- dissociatively adsorbs two water molecules (and methanol), Al5O4- reacts with only one. In addition, Al5O4- does not show any reaction with ammonia while recent experimental and theoretical studies suggest that Al3O3- chemisorbs ammonia. These apparent differences in their chemical reactivity have been explained based on the thermodynamic stability of the corresponding reaction products and kinetic barriers associated with their formation.

    ABSTRACT: Photoelectron spectra of Al(5)O(m)(-) (m=3-5) and of the anion produced by the dissociative adsorption of a water molecule by Al(5)O(4)(-) are interpreted with density-functional geometry optimizations and electron-propagator calculations of vertical electron detachment energies. For Al(5)O(3)(-), Al(5)O(4)(-), and Al(5)O(5)H(2)(-), the observed signals may be attributed to the most stable isomer of each anion. For Al(5)O(5)(-), the features in the photoelectron spectrum are due to three almost isoenergetic isomers.

    ABSTRACT: Several mechanisms proposed and calculated for the sequential oxidation of tungsten suboxide clusters by H(2)O/D(2)O [Mayhall et al., J. Chem. Phys. 131, 144302 (2009)] are evaluated using anion photoelectron spectroscopy of an apparent intermediate, W(2)O(6)D(2) (-). The spectrum of W(2)O(6)D(2) (-) is consistent with the W(2)O(5) (-)+D(2)O-->W(2)O(6) (-)+D(2) intermediate in which the initial water addition involves the interaction of the oxygen from D(2)O with a tungsten atom, approaching from a direction with the least repulsion from the W(2)O(5) (-) oxygen atoms, coupled with the interaction between a deuterium with a tungsten-tungsten bridging oxygen on the cluster. The presence of W(2)O(6)H(2) (-) and W(2)O(6)D(2) (-) suggests that there is insufficient internal energy in the complex to surmount the barrier for rearrangement required for tungsten hydride and hydroxide formation necessary for H(2) or D(2) evolution, which was calculated to be energetically favorable. The quality of the calculations is verified by direct comparison between experimental photoelectron spectra of W(2)O(5) (-) and W(2)O(6) (-) and spectral simulations generated from the lowest energy structures calculated for W(2)O(5) (-), W(2)O(6) (-) and their corresponding neutrals. The results shed light on the importance of repulsion on the pathway a reaction follows under room temperature conditions.
