Among the experimental techniques allowing for the characterization of soft matter systems, NMR diffusometry (NMRD) stands out as a noninvasive and relatively fast method to probe molecular dynamics over large frequency ranges . By providing direct access to segment diffusion and chain relaxation modes, NMRD allows one to probe the dynamics of soft matter systems like hydrated polymers and hydrogels . NMRD has also been successfully used to investigate the surface reorientational dynamics of fluids nanoconfined in high surface-area microporous materials , and is commonly used to study heterogeneous catalytic materials and biomolecules such as proteins . When combined with rheology, NMRD can even provide access to the response of polymer systems under shear .
