NMR active nuclei in group 13 elements
All the group 13 elements possess at least one isotope that is NMR active (Table 1.1).
In particular, routine use is made of 11B NMR spectroscopy in the characterization of B-containing compounds. The 205Tl nucleus is readily observed, and, since Tl behaves similarly to Na and K, replacement of these group 1 metal ions by Tl allows 205Tl NMR spectroscopy to be used to investigate Na- or K-containing biological systems.
