High Resolution NMR: Applications to Biological Systems,erome (1987), Sanders and Hunter (1987), Martin and Crouch (1991), and Wuthrich (1986)). However, rather than examining the vast array of high resolution, multi-dimensional, multi-nuclear experiments that can be performed on proteins, nucleic acids, and small-molecule natural products to determine t

NMR Characterization of Solid Fossil Fuels. Coal and Oil Shale,les, even though the level of chemical shift resolution achieved is limited. The most popular technique .C CP-MAS, is easy and efficient, but requires detailed characterization of the relevant spin dynamics for quantitation. .C MAS experiments that rely on direct polarization (DP) via .C spin-lattic

NMR in Industrial Process Control and Quality Control,terature. Both high-resolution and low-resolution approaches have been used for PC/QC NMR applications; the latter dominate in popularity for a variety of practical reasons and are usually based on low-field magnets that are not capable of high-resolution performance. The most common type of low-fie

Solid State NMR Investigations of Zeolites and Related Materials, introduction to nthe structure and properties of molecular sieves and also to solid-state NMR techniques and go on to describe the application of these NMR techniques to the investigation of low Si-Al ratio materials, emphasizing the experiments on spin one-half nuclei such as .Si and .P. We will t

Averaging Effects in NMR,lar interactions in liquids through random molecular tumbling. These notes will give a general survey of averaging effects, both random and coherent. Attention will be paid to situations where two or more kinds of averaging operate simultaneously and may exhibit interferences, either obnoxious or us

NMR in the Study of Surfaces; 1H CRAMPS and 29Si CP-MAS Studies of Silica,s polarization (CP) provides a largely surface selective .Si approach, although D.O exchange experiments demonstrate that a small percentage of silanols are not accessible to water and hence behave as interior silanols. The .H→.Si CP strategy also permits a correlation of CRAMPS-derived information

NMR of Polymer Composites and Blends,silica are significantly improved when a coupling agent has been added. We show that this coupling agent reacts with the silica surface and partly with the organic polymer. Many investigations have shown that the polymer blend, poly(vinylidenefluoride) (PVDF) and poly(methylmethacrylate) (PMMA), for
