The bonding and electronic structure changes upon adsorption of important functional groups: glycine on copper

Article Abstract:

Using the simplest amino acid, glycine, chemisorbed on Cu(110) and the related model adsorbates formate, acetate, and ammonia, it is demonstrate how x-ray emission spectroscopy can be applied in combination with theoretical calculations to investigate the contribution to the valence molecular orbital from each atom in the molecule. The orbital of importance for the interaction of glycine are strongly localized on the functional groups and are essentially similar in the small model molecules.

X-ray absorption spectroscopy measurements of liquid water

Article Abstract:

A comparison of X-ray absorption spectra of liquid water recorded with five very different techniques sensitive to the local environment of the absorbing molecule is done. The comparison demonstrates that X-ray absorption spectroscopy (XAS) and X-ray Raman scattering (XRS) can be applied reliably to study the local bonding of the water molecule.

(super 15)N solid-state NMR characterization of ammonia adsorption environments in 3A zeolite molecular sieves

Article Abstract:

The quantitative analysis of ammonia binding sites in 3A zeolite molecular sieves using solid-state (super 15)N magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy is reported. (super 15)N MAS NMR is used to elucidate multiple NH3 adsorption environments in 3A zeolite molecular sieves.
