Book Description
This volume contains the lectures presented at an Advanced Study Institute on "Magnetic Resonance Techniques in Fossil Energy Problems," which was held at the village of Maleme, Crete, in July of 1983. As of this writing, a different popular attitude prevails from that when the ASI was proposed as far as how critical the world energy picture is. In the popular press, a panglossian attitude (the "petroleum glut" of the 80's) has replaced the jeremiads of the 70's ( a catastrophic "energy crisis"). Yet, there are certain important constants: (a) for the foreseeable future, fossil energy sources (petroleum, coal, oil shale, etc. ) will continue to be of paramount importance; and (b) science and technology of the highest order are needed to extend the fossil ener~y resource base and to utilize it in a cost-effective manner that is also environmentally acceptable. It is precisely this second item that this volume addresses. The volume introduces the phenomenology of magnetic resonance ~n a unified and detailed manner, starting from the behavior of spins in a magnetic field and proceeding to a density matrix consideration of the phenomena involved. The various important parameters of NMR and EPR are discussed in detail, as well as their significance and the information that may be obtained from their proper consideration. Advanced topics are then considered, including line-broadening interactions, coherent averaging and multiple quantum methods in NMR, ENDOR, electron spin echoes, dynamic nuclear polarization. problems of quantifi cation, 2-Dimensional N}1R, Mossbauer, and instrumentation.

Book Description
Solid state nuclear magnetic resonance now offers a wide variety of methods for characterization of materials of different compositions over a wide range of experimental conditions (temperatures, pressures, etc.) Both simple and sophisticated pulse sequences enable one to selectively probe and quantify physical properties of interest. This book mainly dwells on the practical aspects of selected topics and uses a largely non-mathematical, although extensively referenced, approach to the introduction of solid state NMR concepts. Chapter 1 : Principles of Solid State NMRChapter 2 : Introduction to Pulse SequencesChapter 3 : DecouplingChapter 4 : Quantitative AnalysisChapter 5 : ArtifactsChapter 6 : Line Broadening MechanismsChapter 7 : Resolution EnhancementChapter 8 : Variable Temperature

Book Description
As a spectroscopic method, Nuclear Magnetic Resonance (NMR) has seen spectacular growth over the past two decades, both as a technique and in its applications. Today the applications of NMR span a wide range of scientific disciplines, from physics to biology to medicine. Each volume of Nuclear Magnetic Resonance comprises a combination of annual and biennial reports which together provide comprehensive of the literature on this topic. This Specialist Periodical Report reflects the growing volume of published work involving NMR techniques and applications, in particular NMR of natural macromolecules which is covered in two reports: "NMR of Proteins and Acids" and "NMR of Carbohydrates, Lipids and Membranes". For those wanting to become rapidly acquainted with specific areas of NMR, this title provides unrivalled scope of coverage. Seasoned practitioners of NMR will find this an in valuable source of current methods and applications. Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.

Book Description
Contributed chapters discuss the new magnetic resonance methods for characterizing carbonaceous fuels. Measurements described in the text were made from the same set of Argonne Premium coal samples, so different techniques can be compared with high credibility. A number of nuclear magnetic resonance and electron paramagnetic resonance techniques and results are presented, including solid state NMR spectroscopy and new pulsed EPR techniques.

Book Description
This volume represents the primary lectures of the NATO Advanced Study Institute (ASI) on "Nuclear Magnetic Resonance in Modern Technology," which was held at Sarigerme Park (near the Dalaman Airport) on the southern Aegean shore of Turkey from August 23 to September 4, 1992. As indicated in the title, this ASI was aimed at examining, displaying, and perhaps influencing, the role of nuclear magnetic resonance (NMR) in modern technological activity. The lectures summarized in this volume and the numerous short contributed talks and posters were primarily aimed at the question, "What is NMR doing in support of modern technology?" During the main discussion periods and the numerous small scheduled meetings of specific interest groups this same topic was also addressed, along with questions like, "What could or should NMR be doing in support of modern technology?" With this kind of subject orientation, the organizers attempted to include a large participation at the ASI from scientists and engineers from diverse private industries in which NMR does, or perhaps should, play a substantial role in supporting or optimizing technology. Perhaps because of a combination of worldwide industrial contractions and residual corporate nervousness regarding the then recent Gulf War (which caused a one-year postponement of this ASI), the participation from private industry was numerically disappointing. We hope that this book will serve to bring the role of NMR in modern industry to the attention of numerous industrial scientists and engineers who were unable to attend the AS!.

Book Description
The past decade has witnessed major advances in our understanding of the chemical composition, structure, and reactivity of the complex organic-rich fossil matter known as "coal. " Nevertheless, important scientific questions concerning molecular weight distributions, degree of crosslinking, typical duster sizes, type of interconnecting bridges, the possible role of a "mobile phase," and the nature of organic sulfur forms remain topics of heated debate. Moreover, there appears to be a notable lack of consensus regarding the overall direction and goals of structural elucidation work. Is it worthwhile to study whole coal samples, or should we separate out the various, more or less well-defined, maceral and mineral constituents before attempting to describe the structural and compositional features of coal at the molecular Ievel? Second, should there be more emphasis on key structural features and average statistical parameters, or is it necessary to identify individual chemical structures in considerable detail? From the developments of the past decade it is clear that advanced spectroscopic techniques are playing an increasingly important role in resolving difficult questions with regard to the chemical structure and composition of coal. Moreover, it has become equally clear that no single spectroscopic approach can provide all the answers but multiple techniques need to be used in a highly integrated and synergistic manner.
