Provides a comprehensive explanation of the principles of molecular translational motion measurement using NMR spin echo methods Incorporates a detailed introduction to the principles of NMR spectroscopy, as well as a primer on relevant thermal processes and fluid dynamics Written by one of the world’s leading experts in this field, a scientist responsible for many of the leading developments and discoveries associated with Pulsed Gradient Spin Echo NMR Clearly written in a pedagogical style with introductory essays at the start of each chapter, detailed mathematical derivations, and over 250 figures Targetted at a branch of magnetic resonance which is rapidly growing, and which is finding new applications in chemical engineering, medical MRI, petrophysics, environmental science, food technology Relevant to new technologies based on portable and low field NMR Taking the reader through the underlying principles of molecular translational dynamics, this book outlines the ways in which magnetic resonance, through the use of magnetic field gradients, can reveal those dynamics. The measurement of diffusion and flow, over different length and time scales, provides unique insight regarding fluid interactions with porous materials, as well as molecular organisation in soft matter and complex fluids. The book covers both time and frequency domain methodologies, as well as advances in scattering and diffraction methods, multidimensional exchange and correlation experiments and orientational correlation methods ideal for studying anisotropic environments. At the heart of these new methods resides the ubiquitous spin echo, a phenomenon whose discovery underpins nearly every major development in magnetic resonance methodology. Measuring molecular translational motion does not require high spectral resolution and so finds application in new NMR technologies concerned with ’outside the laboratory’ applications, in geophysics and petroleum physics, in horticulture, in food technology, in security screening, and in environmental monitoring. Readership: Graduate students in physics and chemistry, and professional researchers who are working in nuclear magnetic resonance involving imaging or the study of molecular motion. Also physicists working in medical MRI, as well as physicians wanting a deeper understanding of MRI contrast, and researchers in the food, environmental, or petrochemical industries, who use nuclear magnetic resonance as a research tool.
