Oxygen 17 and Silicon 29

Although it was shown very early [1] that the isotope 29Si is very valuable for NMR research, severe technical difficulties had to be overcome before silicon spectra could be recorded. This was due to the low sensitivity of the isotope resulting from its low gyro magnetic ratio, its low abundance and the rather long relaxation times. The introduction of the Fourier-Transform-Technique (FT-NMR) helped to surmount most of these problems, with the result, that more and more papers concerning silicon NMR appear. Thus, it seems now that most of the salient features of 29Si-NMR are known today. Some resume of the state of the art of 29Si_NMR have been reported [1-4]. Although the theory of 29Si-NMR is not yet understood beyond the basic features, it promises to be of value mainly for two reasons: 1. Silicon is strategically located in the Periodic Table of the elements between the elements carbon, aluminum and phosphorus. For an unified theory of chemical shifts and coupling constants of the heavier elements silicon NMR values will be important. 2. The normal coordination number of silicon is four. If the current view of the chemical shifts of the heavier elements is correct, then the paramagnetic part is dominant for the measured shift data. Two of the parameters used for the calcu lation of the paramagnetic part are bond orders and angles. Bond angles are rare ly determined experimentally with high precision.

17 0 NMR Spectroscopy in Organic Chemistry

This book provides a comprehensive review of the application of 17O NMR spectroscopy to organic chemistry. Topics include the theoretical aspects of chemical shift, quadrupolar and J coupling; 17O enrichment; the effect of steric interactions on 17O chemical shifts of functional groups in flexible and rigid systems; the application of 17O NMR spectroscopy to hydrogen bonding investigations; mechanistic problems in organic and bioorganic chemistry; and 17O NMR spectroscopy of oxygen monocoordinated to carbon in alcohols, ethers, and derivatives. Recent results that show correlations between molecular geometry, determined by X-ray studies and estimated by molecular mechanics calculations, and 17O chemical shifts are also covered. 17O Spectroscopy in Organic Chemistry provides important reference information for organic chemists and other scientists interested in 17O NMR spectroscopy as a tool for obtaining new structural and chemical data about organic molecules.

... and double rotation ( DOR ) techniques were applied in the fields of 17.6 T and
11.7 T to the study the 170 NMR of oxygen - 17 enriched zeolites A , LSX and
sodalite . In addition , some 29 Si and ' H MAS NMR experiments were performed
.

Molecules in Interaction with Surfaces and Interfaces

The study of the interaction of molecules with surfaces and interfaces is of great importance for the understanding of adsorption and catalysis on solid surfaces, the complex properties of molecules on fluid interfaces and the relationship between structure and functionality in macromolecular biological systens. It is the aim of this volume to present and analyse in a comprehensive and accesible way the methodical achievements and the recent proress in this field. The broadness of both scope and selection of the topics should help in particular non-expert readers to become familiar with this exciting field of research.
