title: NMR diffusion: an update.
abstract: NMR diffusion methods continue to attract increasing attention from practising chemists. This short article summarizes some of the more recent developments and highlights the areas in which these methods are finding application, specifically: estimating molecular volumes; investigating the degree of aggregation (especially in salts); studying host-guest interactions; recognizing hydrogen bonds; and directly proving the presence and extent of ion pairing.
