A new approach to the study of surface phenomena, measurements of diffusion rates, intermolecular distances and electronic properties of CO chemisorbed on supported platinum catalysts by nuclear magnetic resonance
… at 77 K can be used to measure relative distances among molecules in the adsorbed layer. His measurements of transverse relaxation and of spin-lattice relaxation are consistent with the geometry of CO layers chemisorbed on single crystal surfaces. He has observed the narrowing of the NMR …

A New Approach to the Study of Surface Phenomena: Measurements of Diffusion Rates, Intermolecular Distances and Electronic Properties of Carbon Monoxide Chemisorbed on Supported Platinum Catalysts by Nuclear Magnetic Resonance
The author has applied magnetic resonance to study the chemisorption of CO on supported platinum particles. The particles are 10 to 50 (ANGSTROM) in diameter, supported on alumina. CO is 90% enriched with ('13)CO. NMR data were taken from 4 K to 600 K.

Transient collagen triple-helix binding to membrane type 1 matrix metalloproteinase : interaction studies and NMR-guided structural docking
… of the triple-helical peptide. Additionally, intermolecular distances between the hemopexin domain of MMP-14 (HPX-14) and THP were measured by paramagnetic NMR using TOAC-labeled THP. Structural models of HPX-14/THP calculated based on PRE-measured distance restraints revealed extensive …

Structural studies of amyloid fibrils using solid-state NMR
… simple and effective way to measure interstrand distances. This method was applied to TTR105.115 fibrils. Several other methods were applied to the TTR fibrils to measure interstrand and intersheet distances including REDOR, TEDOR, R2TRW, and DARR. The intermolecular distances were combined with …

The crystal structure and constitution of some molecular complexes of 4:4- dinitrodiphenyl
… and that in no case is it necessary for the intermolecular distances to be shorter than those found in crystals or ordinary aromatic nitro-compounds. A bonding mechanism in terms of dipole attraction between the component molecules is shown to be consistent with all the observed data. Of …

Characterization of structure and dynamics of membrane proteins from solid-state NMR
… membrane surface-bound MPER. Intra- and intermolecular distances measured using ¹⁹C-¹⁹F REDOR and ¹⁹F-¹⁹F CODEX revealed that MPER-TMD has a significant kink between MPER and TMD, which has aided a deeper understanding of the HIV virus entry mechanism and the design of vaccines.

Investigating the Structure of the Papain-Inhibitor Complex using SPR and NMR
… to various cysteine-mutants of ICP to measure distances to reductively 13C-methylated papain. The modification of ICP with MTSL was quantified using EPR, and the effects of labeling on the binding kinetics of papain and ICP were determined using SPR. 13C-methyl peak perturbations due to PRE …

Heterogeneous Ultrafast Energy Transfer in Photosynthetic Proteins
… transfer rates are exquisitely sensitive to intermolecular distances, which vary within proteins due to thermal fluctuations of the structure. As a result, models predict that the energy transfer rates vary dramatically between proteins, producing some instances of inefficient energy …

The synthesis and characterisation of halogen and nitro phenyl azide derivatives as highly energetic materials
… terminal N(3) atom of the azide group has two intermolecular contacts with two bromine atoms of symetrically related molecules within the unit cell. The intermolecular distances are N(3) to Br(2)* (x – 0.5, -y-0.5, z-0.5) 3.605 Å and N(3) to Br(1)* (x + 1, y, z) 3.881 Å. These distances are …
