Abstract

There are 22 spin-equation image nuclei other than hydrogen and carbon, some with more than one spin-equation image isotope. Four of these, 15N, 19F, 29Si and 31P, have been of major importance in chemistry and nuclear magnetic resonance (NMR) and are the subject of an extensive literature. Many spin-equation image nuclides have had more specialized uses, such as 3H, 77Se, 109Ag, 113Cd, 119Sn, 125Te, 129Xe, 195Pt, 205Tl, and 207Pb. A few have been of limited use, generally due to poor sensitivity: 57Fe, 89Y, 103Rh, 169Tm, 171Yb, 183W, 187Os and 199Hg.

Spin-equation image nuclei generally produce sharp spectral lines, which may allow a wealth of fine structure from spin–spin coupling to be observed. This coupling, along with chemical shift information and dipolar coupling information (nuclear Overhauser effect (NOE)) are used in a variety of ways to obtain structural information and solve chemical problems.

After a brief discussion of analytical techniques, the history, experimental practices, physical properties, relaxation properties, chemical shift referencing, applications and literature references for each nuclide are presented.
