Pulsed-gradient spin-echo NMR (PGSE-NMR) has evolved into a powerful technique for probing colloidal structure, particularly that of complex mixtures. Indeed, with the exception perhaps of neutron scattering, no single technique has such universal applicability. The parameter of interest, the (self-...

PGSE NMRdiffusionnon‐Fickian diffusionmolecular hydrodynamicsFor half a century, pulsed-gradient Spin-Echo NMR based on the Stejskal–Tanner equation has been used to infer Fick's-Law diffusion coefficients of solutes in simple liquids and complex fluids. The decades since the original papers have...
In this work MRI and PGSE NMR have been used to directly study the advanced condensation effect during water adsorption in a macroscopically heterogeneous sol-gel silica pellet. It has been found that capillary condensation will occur at unexpectedly lower pressures in regions of much larger pores ...
Self-diffusion coefficientsof a series of polycyclic charged systems and their parent compounds were measured by using the PGSE NMR method. These data suggest that the dianions of naphthacene2and pyracylene3may exist as dimers with sandwich structure, just like the lithium salt of the tetraanion ...

1H NMR measurements on spin-lattice relaxation time (T1) and spin-spin relaxation time (T2) were carried out on hydro-swollen crosslinked poly(methacrylic acid) (PMAA) gel to elucidate molecular motion of water molecules contained in the gel as a function of the degree of crosslinking. From ...
