The diffusion of alkanes in nanoporous materials as measured by different experimental techniques is thought to be highly dependent on the measuring technique employed. However, when the data are corrected for the loading at which the measurement was performed, the different data series correspond with each other much better than expected.

Abstract Labeling in diffusion measurements by pulsed field gradient (PFG) NMR is based on the observation of phase nuclear spins acquired a constant magnetic with purposefully superimposed gradients. This labeling does no way affect microdynamics and provides information about probability distribution molecular displacements as function time. An introduction measuring principle followed detail...
