The power of solid-state NMR to give crystallographic information has considerably increased since the CPMAS suite of techniques was introduced in 1976. In the first years of the 21st century, the ability of NMR to provide information to support and facilitate the analysis of single-crystal and powder diffraction patterns has become widely accepted. Indeed, NMR can now be used to refine diffraction results and, in favorable cases, to solve crystal structures with minimal (or even no) diffraction data. The increasing ability to relate chemical shifts (including the tensor components) to the crystallographic location of relevant atoms in the unit cell via computational methods has added significantly to the practice of NMR crystallography. Diffraction experts will increasingly welcome NMR as an allied technique in their structural analyses. Indeed, it may be that in the future crystal structures will be determined by simultaneously fitting diffraction patterns and NMR spectra.This Handbook is organised into six sections. The first contains an overview and some articles on fundamental NMR topics, followed by a section concentrating on chemical shifts, and one on coupling interactions. The fourth section contains articles describing how NMR results relate to fundamental crystallography concepts and to diffraction methods. The fifth section concerns specific aspects of structure, such as hydrogen bonding. Finally, four articles in the sixth section give applications of NMR crystallography to structural biology, organic & pharmaceutical chemistry, inorganic & materials chemistry, and geochemistry.About EMR BooksThe Encyclopedia of Magnetic Resonance [EMR] publishes a wide range of online articles on all aspects of MRI and NMR and its applications in medicine, life sciences, chemistry and physics. The Editors regularly commission new articles and updates of existing articles and so EMR is growing year by year. The existence of this growing number of articles, written by the experts in the field, is enabling the publication of a series of EMR Books on specific areas of MRI or NMR. The chapters of this EMR Books will comprise a carefully chosen selection of EMR articles. The EMR Books are intended to be of value and interest to research students, postdoctoral fellows and researchers in hospitals, industry and academia learning about the scientific area in question.Have the content of this EMR Book and the complete content of the Encyclopedia of Magnetic Resonance at your fingertips!
