This book intends to be an easy and concise introduction to the field of
nuclear magnetic resonance or NMR, which has revolutionized life
sciences in the last twenty years. A significant part of the progress
observed in scientific areas like Chemistry, Biology or Medicine can be
ascribed to the development experienced by NMR in recent times. Many of
the books currently available on NMR deal with the theoretical basis and
some of its main applications, but they generally demand a strong
background in Physics and Mathematics for a full understanding. This
book is aimed to a wide scientific audience, trying to introduce NMR by
making all possible effort to remove, without losing any formality and
rigor, most of the theoretical jargon that is present in other NMR
books. Furthermore, illustrations are provided that show all the basic
concepts using a naive vector formalism, or using a simplified approach
to the particular NMR-technique described. The intention has been to
show simply the foundations and main concepts of NMR, rather than
seeking thorough mathematical expressions.
