Les spins nucléaires : des espions pour explorer la structure des matériaux

Abstract : This article illustrates how solid state NMR, which is by nature a local spectroscopic technique, is also able to establish dialogs between nuclear spins over distances up to few nanometers. Access to such length scales is possible through one-dimensional and multidimensional experiments that give chemical signatures not only from one unique atom in relation with its environment, but from groups of atoms chemically bonded or spatially close. In that sense, solid state NMR appears as a perfect investigation tool for materials with more and more complex compositions and structures. The selected examples belong to families of materials that have been developed for applications in the fields of energy (glasses for nuclear waste management), health (hybrid materials for controlled release of drugs) and sustainable development (heterogeneous catalysts).
