NMR crystallography: the use of dipolar interactions in polymorph and co-crystal investigation

The use of dipolar interaction in solid-state NMR spectroscopy represents a powerful tool to access information on chemical structure at molecular level on solid compounds and materials. The study of polymorphs and co-crystals is one of the more active research fields where the possibilities offered by the new emerging NMR crystallography reveal their potential. The aim of this article is to offer the state-of-the-art on this subject in order to develop new insights and to promote cooperative efforts in the fascinating field of polymorphs and co-crystals.
