Abstract 1 H‐chemical shift NMR imaging patterns of a poly(methacrylic acid) gel containing water with paramagnetic praseodymium ions(Pr 3+ ) were successfully observed, in order to elucidate spatial distribution of Pr 3+ ions in the gel. The 1 H chemical shift of water associated with Pr 3+ ions in the gel moves largely downfield. By analyzing these experimental results, the immersion process of Pr 3+ ions into the network of the polymer gel was spatially clarified. Further, it is shown that the chemical shift NMR imaging method is a useful means for determining the spatial distribution of paramagnetic metal ions in polymer gels.
