Description:

Remains the only book which sets out the theory of NMR in an accessible and comprehensible manner, avoiding excessive mathematics and taking the reader step by step though the argument. Completely new page layout incorporating extensive use of a second colour Inclusion of material on chemical exchange, spin-system analysis and the behavior of AX2 and AC3 spin systems Addition of interactive web-based resources for the book which go beyond simply reproducing the figures. Each chapter with tested exercises. Incorporating feedback from course participants and internet users.
