| Abstract: | The principles and main limitations of the application of the NMR field gradient technique to self-diffusion measurements are discussed. Due to their higher sensitivity for small diffusion coefficients and due to several advantages with the analytical treatment of the experimental data, the pulsed gradient methods are of special importance for the investigation of heterogeneous systems. Examples of the application of these techniques to diffusion studies in multicomponent systems and bounded media are given. |
