New developments in high‐resolution multidimensional NMR of solids are described. Special emphasis is placed on double‐quantum (DQ) methods employing fast magic angle spinning (MAS). This new technique allows structural elucidation with atomistic resolution including hydrogen positions in non‐crystalline materials and the determination of the anisotropy of chain motions by probing residual dipolar couplings between adjacent groups along a macromolecule. Specific examples include hydrogen bonded systems, columnar structures with π‐π interactions, polymer melts and block copolymers.
