Roman Meier, Prof. Danuta Kruk and Prof. Ernst A. Rössler Intermolecular Spin Relaxation and Translation Diffusion in Liquids and Polymer Melts: Insight from Field-Cycling 1H NMR Relaxometry ChemPhysChem 14
Going through the motions: The time correlation function reflects molecular rotation as well as translation in liquids and polymers. The two contributions can be separated (see picture). The power law of the long-time tail of the correlation function gives direct access to the diffusion coefficient.
