With nearly 400 original illustrations, this NMR primer provides an introduction to solution NMR spectroscopy at a level appropriate for advanced undergraduates, graduate students and working scientists with backgrounds in chemistry or biochemistry. It presents the underlying physics and mathematics in a way that is both accessible and sufficiently complete to allow a real understanding of modern multi-dimensional experiments, thereby giving readers the tools they need to move to more advanced textbooks and articles. One special feature of this text is a thorough, but accessible, treatment of spin quantum mechanics, including scalar-coupled spins. A novel style of vector diagram is used to represent the quantum correlations between coupled spins and the manipulation of these correlations by pulses and time evolution. This will help to clarify what is arguably the most difficult aspect of NMR for students and practitioners to master.
