Nuclear magnetic resonance (NMR) has proved to be a uniquely powerful and versatile spectroscopy, and no modern university chemistry department or industrial chemistry laboratory is complete without a suite of NMR spectrometers. The phenomenon of nuclear spin may seem an odd basis for an analytical tool, but it is the relative isolation of the nuclear spin from its surroundings that makes it an ideal noninterfering probe of the electronic environment. Different sites are clearly identified by their chemical shifts, while J couplings in 1H spectra provide connectivity information. The combination of these two complementary interactions, plus the formidable array of different NMR experiments developed since the arrival of Fourier transform NMR in 1966, has revolutionized the practice of chemistry.

The book is intended to help under- and postgraduate students and young scientists in the correct application of NMR to the solution of physico-chemical problems concerning the study of equilibria in solution. The first part of the book (Chapters 1-3) is a trivium, but should enable a student to design and conduct simple physico-chemical NMR experiments. The following chapters give illustrative material on the physico-chemical applications of NMR of increasing complexity. These chapters include the problem of determination of equilibrium and rate constants in solution, the study of paramagneti

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.
