O livro intitulado Espectroscopia de Ressonância Magnética Nuclear é um texto atualizado destinado a químicos mas acessível a não especialistas que necessitem de alguns conhecimentos fundamentais desta hoje importantíssima técnica. O trabalho constitui uma atualização de um primeiro trabalho dos mesmos autores publicado alguns anos atrás, tendo em conta a importante evolução instrumental bem como das técnicas bidimensionais. Os autores esperam com este novo trabalho ter colocado à disposição dos leitores um trabalho que satisfaz os principais requisitos atuais de quem precisa da espectroscopia de ressonância magnética nuclear como um método de suporte à resolução de problemas estruturais.

Nuclear magnetic resonance (NMR) has evolved as a versatile tool in chemistry and biology. This scientific technique is based on the detection of magnetic moments of atomic nuclei arising due to an intrinsic property called spin because of their precession in static magnetic fields. Nuclei are excited by radio frequency (RF) magnetic fields and subsequently their precession is observed by the voltage they induce on an induction coil as they precess. In this book, we present some of the most exciting developments in the field of NMR: for example, new developments in NMR instrumentation, new magnet technology, RF coil design, the design of novel NMR sensors, and new developments of methods in solution and solid-state NMR These range from new methods for the fast acquisition of 2D spectrum to NMR studies of molecular interactions in ionic solutions. Solid-state methods for the analysis of polyvinyl chloride and NMR studies of torsion angles in polypeptides are also included. The book will be a useful reference for practitioners in the field and at the same time will appeal to a broad audience interested in the general area of NMR.

Nuclear Magnetic Resonance (NMR) spectroscopy is a nondestructive technique that can be used to characterize a wide variety of systems. Sustained development of both methodology and instrumentation have allowed NMR to evolve as a powerful technology, with applications in pure sciences, medicine, drug development, and important branches of industry. NMR provides precise structural information down to each atom and bond in a molecule, and is the only method for the determination of structures of molecules in a solution. This book compiles a series of articles describing the application of NMR in a variety of interesting scientific challenges. The articles illustrate the versatility and flexibility of NMR.
