Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - The field of nuclear magnetic resonance has experienced a number of spectacular developments during the last decade. Fourier transform methodology revolutionized signal acquisition capabilities. Superconducting magnets enhanced sensitivity and produced considerable improvement in spectral dispersion. In areas of new applicat ions, the life sciences particularly bene fited from these developments and probably saw the largest increase in usage. NMR imaging promises to offer a noninvasive alternative to X rays. High resolution is now achievable with solids, through magic angle spinning and cross polarization, so that the powers of NMR are applicable to previously intractable materials such as polymers, coal, and other geochemicals. The ease of obtaining relaxation times brought an important fourth variable, after the chemical shift, the coupling constant, and the rate constant, to the examination of structural and kinetic problems i~ all fields. Software development, particularly in the area of pulse sequences, created a host of useful tech niques, including difference decoupling and difference nuclear Overhauser effect spectra, multidimensional displays, signal enhancement (INEPT), coupling constant analysis for connectivity (INADEQUATE), and observation of specific structural classes such as only quaternary carbons. Finally, hardware development gave us access to the entire Periodic Table, to the particular advan tage of the inorganic and organometallic chemist. At the NATO Advanced Study Institute at Stirling, Scotland, the participants endeavored to examine all these advances, except imaging, from a multidisciplinary point of view.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The last decade has been characterized by a growing interest in liquid crystalline materials of increasing complexity (ferroelectrics, biaxial nematics, elastomers, dendrimers, etc.). The fundamental research on these materials, showing an optimal response to external stimula (e.g. electric and magnetic fields), is aimed to prepare the way to new technological breakthroughs. This book provides an extensive overview of how ab initio calculations combined with Nuclear Magnetic Resonance can be an indispensable tool to understand the relation among specific molecular structures, orientational ordering and the resulting magnetic, electrical and optical anisotropic responses shown by the mesophases formed. The integrated use of quantum-mechanical methods and NMR techniques clearly shows that the modeling is not only extremely useful to support the measurements but it becomes compulsory to go beyond the observable towards a deeper molecular-based knowledge of materials. This volume is aimed at graduate students, novices, librarians and experts around the world. It, indeed, provides a good reference material for readers interested in the liquid crystal research.…
