The list of nuclei in the previous question are just commonly used ones in NMR experiments. Other elements are observable, but sometimes these require special hardware to obtain useful signal levels. Some of these other nuclei that can be studied by NMR are ¹⁷O, ²⁹Si, ³³S, ⁷⁷Se, ⁸⁹Y, ¹⁰³Rh, ¹¹⁷Sn, ¹¹⁹Sn, ¹²⁵Te, ¹⁹⁵Pt, ¹¹¹Cd, ¹¹³Cd, ¹²⁹Xe, ¹⁹⁹Hg, ²⁰³Tl, ²⁰⁵Tl, and ²⁰⁷Pb.
