Solid-State NMR and Organic Geochemistry explains solid-state NMR from the point of view of organic geochemists interested in applying solid-state NMR in their research. The book sets the scene in the first two chapters by describing the basic concepts of solid-state NMR adapted for non-NMR specialists as well as an overview of organic geochemistry for NMR specialists. The essentials for acquiring reliable spectra of complex organic matter are then described in Chapter 3. Chapter 4 introduces the systematic and advanced solid-state NMR techniques and approach to characterizing complex organic mixtures developed in Dr. Mao's laboratory. Practical aspects of performing solid-state NMR experiments of complex organic matter are discussed in Chapter 5. Chapters 6 through 15 are focused on applications of solid-state NMR in organic geochemistry, starting with geochemically important functional groups and biopolymers, followed by organic matter from soils, water, sediments, and aerosols, peat, coal, kerogen, and oil shale. The interactions of organic matter with organic contaminants probed by solid-state NMR are described in Chapter 16. Finally, the last chapter covers isotopic enrichment and labelling and solid-state NMR, and their applications in organic geochemistry. Bridges the gap between NMR specialists and organic geochemists, adapting solid-state NMR theory for non-NMR specialists Brings together NMR applications for a range of materials not often discussed in other NMR books, including applications to soil, aerosols, peat, coal, kerogen, and more Includes additional resources for further reading and problems to facilitate learning and application of key concepts in each chapter

Solid-State NMR is a branch of Nuclear Magnetic Resonance which is presently experiencing a phase of strongly increasing popularity. The most striking evidence is the large number of contributions from Solid-State Resonance atNMR meetings, approaching that ofliquid state resonance. Important progress can be observed in three areas: Methodological developments, applications to inorganic matter, and applications to organic matter. These developments are intented to be captured in three volumes in this series, each of them being devoted to more or less one of these areas. The present volume on Solid-State NMR III is devoted mainly to organic matter. The recent developments of deuteron NMR and their applications are reviewed in the first chapter. Crosspolarization, MAS, and dynamic angle spinning are being explored for enhancement of information and sensitivity. In addition to the analysis of classical relaxation times and modern 2D spectra, detailed dynamic information becomes accessible from investigations of the relaxation time anisotropies. The second chapter examines cross-polarization in static and rotating solids under conditions of spin diffusion and thermal motion. The underlying dipole-dipole interaction is further exploited by the techniques described in the third chapter for studies of polymer-polymer miscibility. Short range techniques are discriminated from long-range techniques based on spin diffusion. The use ofthese techniques is illustrated by a case study ofPMMAJPVF blends. The last chapter addresses novel z methods and applications of two-dimensional exchange NMR for investigations of relative molecular orientations, polymer morphology, molecular dynamics, and macroscopic molecular order.

The book provides an in-depth review of the state of the art of NMR spectroscopy as applied to a wide range of geochemical problems. It is intended to assist geochemists and spectroscopists working at the interface between geochemistry and NMR, and almost all areas of organic and inorganic geochemistry where NMR has had an influence are discussed.

Solid-state NMR is a powerful physical method widely applied in modern fundamental and applied science, medicine, and industry. Its role is particularly valuable in materials chemistry due to the capability of solid-state NMR to rapidly solve tasks connected with structural descriptions of complex systems on macro and/or molecular levels, and the i

As this is the first general textbook for the field published in over twenty years, the editors have taken great care to make sure coverage is comprehensive. Diagenesis of organic matter, kerogens, exploration for fossil fuels, and many other subjects are discussed in detail to provide faculty and students with a thorough introduction to organic geochemistry.

Solid-State NMR is a branch of Nuclear Magnetic Resonance which is presently experiencing a phase of strongly increasing popularity. The most striking evidence is the large number of contributions from Solid-State Resonance at NMR meetings, approaching that ofliquid state resonance. Important progress can be observed in the areas of methodological developments and applications to organic and inorganic matter. One volume devoted to more or less one of each of these areas has been published in the preceding three issues. This volume can be considered an addendum to this series. Selected methods and applications of Solid-State NMR are featured in three chapters. The first one treats the recoupling of dipolar interactions in solids, which are averaged by fast sample rotation. Following an introduction to effective Hamiltonians and Floquet theory, different types of experiment such as rotary resonance, dipolar chemical shift correlation spectroscopy, rotational resonance and multipulse recoupling are treated in the powerful Floquet formalism. In the second chapter, the different approaches to line narrowing of quadrupolar nuclei are reviewed in a. consistent formulation of double resonance (DaR) and dynamic angle spinning (DAS). Practical aspects of probe design are considered as well as advanced 2D experiments, sensitivity enhancement techniques, and spinning sideband manipulations. The use of such techniques dramatically increases the number of nuclei which can be probed in high resolution NMR spectroscopy. The final chapter describes new experimental approaches and results of structural studies of noncrystalline solids.
