Measurement of self-diffusion in thin samples using a novel one-sided NMR magnet

- A novel one-sided NMR magnet has been validated for measurements of self-diffusion in thin samples (⩽1 mm).
- 1H self-diffusion has been measured for an ionic liquid confined (IL) in porous alumina membranes.
- A reduced diffusion coefficient, compared to the bulk, has been observed for the confined IL.
