title: Recent advances in solid-state MAS NMR methodology for probing structure and dynamics in polymeric and supramolecular systems.
abstract: This article reviews recent applications of novel (1) H, (2) H, (13) C, (15) N and (17) O solid-state MAS NMR methods that provide new insight into the structural and dynamic processes that determine the bulk properties of polymeric and supramolecular materials. The review highlights methods that exploit the sensitivity to structure and dynamics of the NMR chemical shift and quadrupolar coupling as well as the through-space dipolar coupling and through-bond J coupling. In particular, it is shown that solid-state NMR exhibits marked sensitivity to key intra- and intermolecular hydrogen-bonding and π-π interactions, allowing, for example, the very accurate determination of internuclear distances as well as the probing of dynamics over a very wide range of timescales.
