Introduction to the Interactions of NMR and Their Application to NMR Crystallography

This chapter provides a brief overview of the key interactions of NMR (shielding, quadrupolar, dipolar and J coupling interactions) and their relationship to NMR crystallography. It provides an accessible introduction to the use of solid-state NMR for structural characterisation, highlighting how the crystallographic information available depends on the individual NMR isotope and on the nature of the material. The structural information available from NMR is illustrated with examples from both organic and inorganic materials for the different NMR interactions. Theoretical discussion is limited to key topics, such as the tensor nature of NMR interactions, that will be assumed in later chapters of this volume.
