Peptide [super17]O chemical shielding and electric field gradient tensors
Article Abstract:
A study determined complete [super 17]O chemical shielding (CS) and quadrupole coupling (QC) tensors and their molecular orientations for the central residues in two tripeptides Gly-Gly-Val (GGV) and Ala-Gly-Gly (AGG) by single-crystal NMR methods. Results lead to the anticipation that [super17]O NMR should be generally useful for probing H-bonding and local electrostatic interactions in proteins and polypeptides.

Pressure effect on the optical bandshape of solid oxygen
Article Abstract:
A study is conducted to measure and model pressure effects on the optical band shape of vibronic two-molecule transitions. The conclusion states that the total band intensity increases with pressure as the combined excitations are assisted by intermolecular exchange interaction due to the decrease in the distance between molecules participating in this transition.

Effect of oxygen precoverage on the reactivity of methanol on Ru(001) surfaces
Article Abstract:
The reflection-absorption infrared spectroscopy (RAIRS) is used, under ultra-high vacuum conditions, to investigate the thermal decomposition of methanol on oxygen modified Ru(001) surfaces. The specific ways in which the oxygen coverage determines the stability of the reaction intermediates are discussed.
