This book provides a particular approach to the application of NMR spectroscopy for the characterization of structural and behavioral aspects of solids with the aim of resolving details at the local scale. The book is divided in four parts. The first part is dedicated to a basic and general theoretical background on the technique. The next section consist of five chapters on the contribution of NMR in the study of crystalline and non-crystalline solids, including minerals, ceramics, cements, glasses and glass-ceramics, in order to explore the local structure in that variety of natural and synthetic materials. The third part deals with materials and compounds of interest in catalysis, energy production, transformation, storage and related applications. Finally, the fourth section focuses on the characterization of active pharmaceutical ingredients, polymers and solid proteins. Aimed at dissemination of solid state NMR, this volume is an essential reading for researchers and students of solid-state science, but also a very useful instrument for academic teaching. Luis Sánchez-Muñoz received his PhD degree on his thesis in Applied Mineralogy from the Universidad Complutense de Madrid in 1992. He occupies the position of senior scientist of the Consejo Superior de Investigaciones Científicas (CSIC) since 2009 and, particularly, in the Museo Nacional de Ciencias Naturales (MNCN-CSIC) since 2019. His research interests include, among others, the explanation of the crystalline order from NMR data by using mineral structures.
