Transported in single file : Expressions for the hyperpolarized NMR saturation recovery signals of single‐file diffusion in L ‐alanyl‐ L ‐valine (AV) nanotubes are derived and compared to experiments. The distribution of hyperpolarized Xe inside a single channel with increasing observation time τ is shown schematically.
