Book Description
The revolutionary impetus of the NMR methods in organic chemistry has parallels in the field of boron chemistry. lIB NMR spectroscopy provided a basis for the elucida tion of structures and reactions of the boron hydrides. However, although many studies have been carried out with the higher boranes, carboranes, metalloboranes, etc. , and although certain patterns have emerged, the correlation between the observed chemical shift and the assigned structural unit is still not fully understood. Therefore, predictions in this area are still rather limited, and semiquantitative interpretations are not yet pos sible. Several years ago Eaton and Lipscomb sUpImarized the status in this field in their book "NMR Studies of Boron Hydrides and Related Compounds" and a plethora of new data has accumulated since then. The book also contained material on simple bo rane derivatives, but they were not discussed in any detail. On the other hand many systematic studies, both synthetic and spectroscopic, have been conducted on these simple boron materials in the last decade. Thus a large amount of NMR information is available, not only on lIB but also on 1 H, 1 3 C, and 14 N. However, this information is widely scattered in the literature, and often the data are not discussed at all. It see med appropriate, therefore, to collect these data and to present them in one volume.

Book Description
The goal of this book is to provide an introduction to the practical use of mobile NMR at a level as basic as the operation of a smart phone. Each description follows the same didactic pattern: introduction, basic theory, pulse sequences and parameters, beginners-level measurements, advanced-level measurements, and data processing. Nuclear Magnetic Resonance (NMR) spectroscopy is the most popular method for chemists to analyze molecular structures while Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic tool for medical doctors that provides high-contrast images of biological tissue depicting the brain function and the beating heart. In both applications large super-conducting magnets are employed which magnetize atomic nuclei of an object positioned inside the magnet. Their circulating motion is interrogated by radio-frequency waves. Depending on the operating mode, the frequency spectrum provides the chemist with molecular information, the medical doctor with anatomic images, while the materials scientist is interested in NMR relaxation parameters, which scale with material properties and determine the contrast in magnetic resonance images. Recent advances in magnet technology led to a variety of small permanent magnets, by which NMR spectra, images, and relaxation parameters can be measured with mobile and low-cost instruments.

Book Description
This book describes the advanced developments in methodology and applications of NMR spectroscopy to life science and materials science. Experts who are leaders in the development of new methods and applications of life and material sciences have contributed an exciting range of topics that cover recent advances in structural determination of biological and material molecules, dynamic aspects of biological and material molecules, and development of novel NMR techniques, including resolution and sensitivity enhancement. First, this book particularly emphasizes the experimental details for new researchers to use NMR spectroscopy and pick up the potentials of NMR spectroscopy. Second, the book is designed for those who are involved in either developing the technique or expanding the NMR application fields by applying them to specific samples. Third, the Nuclear Magnetic Resonance Society of Japan has organized this book not only for NMR members of Japan but also for readers worldwide who are interested in using NMR spectroscopy extensively.

Book Description
The idea that a long-lived form of spin order, namely singlet order, can be prepared from nuclear spin magnetisation first emerged in 2004. The unusual properties of singlet order–its long lifetime and the fact that it is NMR silent but interconvertible into other forms of NMR active order—make it a ‘smart tag’ that can be used to store information for a long time or through distant space points. It is not unexpected then, that since its first appearance, this idea has caught the attention of research groups interested in exploiting this form of order in different fields of research spanning from biology to materials science and from hyperpolarisation to quantum computing. This first book on the subject gives a thorough description of the various aspects that affect the development of the topic and details the interdisciplinary applications. The book starts with a section dedicated to the basic theories of long-lived spin order and then proceeds with a description of the state-of-the-art experimental techniques developed to manipulate singlet order. It then concludes by covering the generalization of the concept of singlet order by introducing and discussing other forms of long-lived spin order.

Book Description
Nuclear Magnetic Resonance Spectroscopy, Second Edition focuses on two-dimensional nuclear magnetic resonance (NMR) spectroscopy, high resolution NMR of solids, water suppression, multiple quantum spectroscopy, and NMR imaging. The selection first takes a look at the fundamental principles and experimental methods. Discussions focus on the NMR phenomenon, dipolar broadening and spin-spin relaxation, nuclear electric quadrupole relaxation, saturation, magnetic shielding and chemical shift, magnetic field, transitions between the nuclear energy levels, and resolution and sensitivity considerations. The manuscript then ponders on chemical shift, coupling of nuclear spins, and nuclear relaxation and chemical rate processes. Topics include spin lattice relaxation, spin-spin relaxation, spin decoupling and associated techniques, and description and analysis of spin systems. The text examines two-dimensional NMR spectroscopy, macromolecules, and NMR of solids, including magic angle spinning, cross polarization, proton dipolar broadening, biopolymers, and chain motion in macromolecules. The selection is a valuable source of data for readers interested in nuclear magnetic resonance spectroscopy.

Book Description
NMR Imaging in Biomedicine: Advances in Magnetic Resonance discusses significant advances in NMR imaging and its application to the field of biomedicine. This book is organized into 10 chapters that cover the classification, methods, imaging regimes, and the potential use of NMR imaging in medicine. After discussing the basic theoretical ideas of NMR and its application to NMR imaging, this book presents mathematical analyses of the various NMR techniques, focusing primarily on the comparison in terms of imaging speed and data-acquisition rate. It also covers a number of practical ranges or imaging regimes in terms of sensitivity, sample size, and operating frequency. Significant topics on potential application of NMR imaging in medicine, apparatus requirements in the instrumentation of NMR imaging machines, and the principles of biomagnetic effects are discussed in other chapters. The considered biomagnetic effects are categorized into three main groups: the effects of static magnetic fields, the effects of relatively slow varying time-dependent fields, and radio-frequency magnetic fields. This book is of great value to radiologists, medical physicists, neuroradiologists, anatomists, physiologists, and postgraduate students of NMR imaging.

Book Description
High Resolution NMR in Solids: Selective Averaging presents the principles and applications of the four approaches to high resolution NMR in solids — magic-angle sample spinning, multiple-pulse, proton-enhanced nuclear induction, and indirect detection methods. Divided into six chapters, this book initially describes the tensorial properties of nuclear spin interactions in both ordinary and spin spaces. It then deals with the manifestations of nuclear magnetic shielding in NMR spectra of both single-crystal and powder samples, and then discusses the techniques for analyzing spectra and rotation patterns in terms of shielding tensors. A wide range of NMR phenomena that are result of intentional or natural, selective or unselective averaging processes and the average Hamiltonian theory that yields the inclusion of correction are covered. This book also provides a detailed discussion on multiple-pulse sequences intended for high resolution NMR in solids. The concluding chapter examines the applications of multiple-pulse techniques, with particular emphasis on measurements of 19F and 1H shielding tensors. Discussions on rotations of angular momentum operators; time ordering and the Magnus expansion; off-resonance averaging of the second-order dipolar Hamiltonian; and phase transients are covered in the supplemental texts.
