While NMR is the most used analytical method for determining the molecular structure of
isolated chemical entities, small compounds as well as macromolecules, its capability of
analysing complex mixtures is less known. The advent of Diffusion Ordered SpectroscopY
(DOSY) NMR has made diffusion experiments popular, enabling diffusion coefficients to be
routinely measured and used to characterize chemical systems in solution. Indeed, since the
translational diffusion coefficients of molecular species reflect their effective sizes and …

Pulsed-field gradient nuclear magnetic resonance (PFG-NMR) is a widely used method for
determining the diffusion coefficient of ions and molecules both in the bulk and when
confined (eg, within porous materials). Due to the nature of diffusion phenomena and the
correlation of these processes with the structures of isolated molecules or clusters, studies of
diffusion can be used to extract both dynamic and structural information from complex
mixtures, including battery electrolytes composed of cations, anions, and solvent molecules …
