An experiment is presented that combines the techniques of multiple-quantum magic-angle spinning (MQMAS) and cross-polarization (CP) between spin-1/2 and half-integer quadrupolar spin nuclei. This technique, referred to as CP MQMAS, allows the coordination of the spin-1/2 nuclei within a quadrupole system to be determined, which demonstrates its usefulness for spectral editing. The radio-frequency (rf) pulse sequences and necessary phase-cycling are developed and examined. A novel approach of incorporating a 'z-filter' between the two techniques allowed us to optimize our new procedure, CP MQMAS, as two unique experiments prior to their coupling. Experimental details concerning the manipulations necessary to produce and detect multiple-quantum (MQ) NMR spectra of half-integer quadrupole nuclei are presented.

NMR OF QUADRUPOLAR NUCLEI IN SOLID MATERIALS Over the past 20 years technical developments in superconducting magnet technology and instrumentation have increased the potential of NMR spectroscopy so that it is now possible to study a wide range of solid materials. In addition, one can probe the nuclear environments of many other additional atoms that possess the property of spin. In particular, it is possible to carry out NMR experiments on isotopes that have nuclear spin greater that 1⁄2 (i.e. quadrupolar nuclei). Since more that two-thirds of all NMR active isotopes are quadrupolar nuclei, applications of NMR spectroscopy with quadrupolar nuclei are increasing rapidly. The purpose of this handbook is to provide under a single cover the fundamental principles, techniques and applications of quadrupolar NMR as it pertains to solid materials. Each chapter has been prepared by an expert who has made significant contributions to out understanding and appreciation of the importance of NMR studies of quadrupolar nuclei in solids. The text is divided into three sections: The first provides the reader with the background necessary to appreciate the challenges in acquiring and interpreting NMR spectra of quadrupolar neclei in solids. The second presents cutting-edge techniques and methodology for employing these techniques to investigate quadrupolar nuclei in solids. The final section explores applications of solid-state NMR studies of solids ranging from investigations of dynamics, characterizations of biological samples, organic and inorganic materials, porous materials, glasses, catalysts, semiconductors and high-temperature superconductors. About EMR Handbooks The Encyclopedia of Magnetic Resonance (EMR) publishes a wide range of online articles on all aspects of magnetic resonance in physics, chemistry, biology and medicine. The existence-of this large number of articles, written by experts in various fields, is enabling the publication of a series of EMR Handbooks on specific areas of NMR and MRI. The chapters of each of these handbooks will comprise a carefully chosen selection of Encyclopedia articles. In consultation with the EMR Editorial Board, the EMR Handbooks are coherently planned in advance by specially-selected Editors, and new articles, are written (together with updates of some already existing articles) to give appropriate complete coverage. The handbooks are intended to be of value and interest to research students, postdoctoral fellows and other researchers learning about the scientific area in question and undertaking relevant experiments, whether in academia or industry.

Energy storage material is a hot topic in material science and chemistry. During the past decade, nuclear magnetic resonance (NMR) has emerged as a powerful tool to aid understanding of the working and failing mechanisms of energy storage materials and devices. The aim of this book is to introduce the use of NMR methods for investigating electrochemical storage materials and devices. Presenting a comprehensive overview of NMR spectroscopy and magnetic resonance imaging (MRI) on energy storage materials, the book will include the theory of paramagnetic interactions and relevant calculation methods, a number of specific NMR approaches developed in the past decade for battery materials (e.g. in situ, ex situ NMR, MRI, DNP, 2D NMR, NMR dynamics) and case studies on a variety of related materials. Helping both NMR spectroscopists entering the field of batteries and battery specialists seeking diagnostic methods for material and device degradation, it is written by leading authorities from international research groups in this field.

Nuclear magnetic resonance (NMR) is an analytical tool used by chemists and physicists to study the structure and dynamics of molecules. In recent years, no other technique has gained such significance as NMR spectroscopy. It is used in all branches of science in which precise structural determination is required and in which the nature of interactions and reactions in solution is being studied. Annual Reports on NMR Spectroscopy has established itself as a premier means for the specialist and non-specialist alike to become familiar with new techniques and applications of NMR spectroscopy.

Solid-state NMR covers an enormous range of material types and experimental techniques. Although the basic instrumentation and techniques of solids NMR are readily accessible, there can be significant barriers, even for existing experts, to exploring the bewildering array of more sophisticated techniques. In this unique volume, a range of experts in different areas of modern solid-state NMR explain about their area of expertise, emphasising the “practical aspects” of implementing different techniques, and illustrating what questions can and cannot be addressed. Later chapters address complex materials, showing how different NMR techniques discussed in earlier chapters can be brought together to characterise important materials types. The volume as a whole focusses on topics relevant to the developing field of “NMR crystallography” – the use of solids NMR as a complement to diffraction crystallography. This book is an ideal complement to existing introductory texts and reviews on solid-state NMR. New researchers wanting to understand new areas of solid-state NMR will find each chapter to be the equivalent to spending time in the laboratory of an internationally leading expert, learning the hints and tips that make the difference between knowing about a technique and being ready to put it into action. With no equivalent on the market, it will be of interest to every solid-state NMR researcher (academic and postgraduate) working in the chemical sciences.
