Download or read book Solid State NMR IV Methods and Applications of Solid State NMR written by B. Blümich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Spectroscopy of Condensed Media written by C.H. Wang and published by Elsevier. This book was released on 2012-12-02 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopy of Condensed Media: Dynamics of Molecular Interactions discusses the use of molecular spectroscopy (including nuclear magnetic resonance [NMR] and nonlinear optical spectroscopy) in dynamic processes in condensed molecular systems. The book reviews relationship between transition probability and the time-correlation function of an isotropic electric dipole system, linear-response theory, and light scattering resulting from the translational motion of molecules in fluids. The text describes molecular rotation, theories of angular momentum, nuclear magnetic resonance, and spontaneous and coherent Raman effects. Closely related with the Raman and Brillouin scattering are vibrational dephasing, relaxation processes, and dynamics of phase transition solids. The book highlights the advantages of using NMR and also explains the basic concepts, such as local field, spin temperature, and effective Hamiltonians, that are employed in interpreting NMR experiments. The investigator can use nonlinear optical spectroscopy to study condensed matter. The text also cites two methods in which the investigator can control the time-dependent average Hamiltonian by (1) manipulating the intensity, timing, phase of the pulses, or (2) by sample spinning. The book is intended for advanced graduate students in physical chemistry that will equally benefit both investigators and scientists involved in physics research.

Download or read book Cross relaxation and Cross correlation Parameters in NMR written by Daniel Canet and published by Royal Society of Chemistry. This book was released on 2017-10-18 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spin relaxation parameters, although difficult to interpret, are attracting interest in NMR as these parameters are capable of yielding both structural and dynamic information. Cross-relaxation and cross-correlation parameters afford a non-ambiguous approach to molecular structure and dynamics although they require some special skills for their experimental determination and for their exploitation. This work will start with an introduction to nuclear spin cross-relaxation and cross-correlation phenomena in liquids then look in more detail at molecules in soft matter and large biomolecules. Providing a detailed, timely account, the authors are filling a gap in the present NMR literature for the analytical scientist.
Download or read book Modern Methods in Solid state NMR written by Paul Hodgkinson and published by Royal Society of Chemistry. This book was released on 2018-04-05 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Solid State NMR Spectroscopy written by Melinda J. Duer and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for those familiar with solution-state NMR who are encountering solid-state NMR for the first time. It presents the current understanding and applications of solid-state NMR with a rigorous but readable approach, making it easy for someone who merely wishes to gain an overall impression of the subject without details. This dual requirement is met through careful construction of the material within each chapter. The book is divided into two parts: "Fundamentals" and "Further Applications." The section on Fundamentals contains relatively long chapters that deal with the basic theory and practice of solid-state NMR. The essential differences and extra scope of solid-state NMR over solution-state is dealt with in an introductory chapter. The basic techniques that all chapters rely on are collected into a second chapter to avoid unnecessary repetition later. Remaining chapters in the "Fundamentals" part deal with the major areas of solid-state NMR which all solid-state NMR spectroscopists should know about. Each begins with an overview of the topic that puts the chapter in context. The basic principles upon which the techniques in the chapter rely are explained in a separate section. Each of these chapters exemplifies the principles and techniques with the applications most commonly found in current practice. The "Further Applications" section contains a series of shorter chapters which describe the NMR techniques used in other, more specific areas. The basic principles upon which these techniques rely will be expounded only if not already in the Fundamentals part.

Download or read book Dielectrics in Time Dependent Fields written by Bozzano G Luisa and published by Elsevier. This book was released on 2012-12-02 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theory of Electric Polarization, Volume II: Dielectrics in Time-Dependent Fields focuses on the processes, reactions, and principles involved in the application of dielectrics in time-dependent fields, as well as the Kerr effect, statistical mechanics, and polarization. The publication first examines the phenomenological theory of linear dielectrics in time-dependent fields; empirical description of dielectric relaxation; and the relationship between macroscopic and molecular dielectric relaxation behavior. Concerns cover the relationship between macroscopic and microscopic correlation functions; statistical mechanics of linear dissipative systems and the relationship between response functions and correlation functions; superpositions of distribution functions; and the use of complex dielectric constant in problems with time-dependent field sources. The book then ponders on the dipole correlation function, polarization in the infrared and optical frequency range, and the Kerr effect and related phenomena. Discussions focus on the Kerr effect in condensed systems, extensions of the Kerr effect, extrapolation of the refractive index to infinite wavelength, results obtained from computer simulations, rotational diffusion, and general aspects of molecular reorientation. The manuscript tackles the dielectric properties of molecular solids and liquid crystals and experimental determination of permanent dipole and quadrupole moments. The text is a valuable source of data for researchers interested in the application of dielectrics in time-dependent fields.
