There are many nuclei which are NMR active. The table below shows some
of the more common ones. Despite this, most NMR data are collected for
1H and 13C since they are so important in organic
chemistry.
| Isotope | % abund | Nuclear spin |
| 1H | 99.985 | 1/2 |
| 13C | 1.108 | 1/2 |
| 2H | 0.015 | 1 |
| 11B | 80.42 | 3/2 |
| 14N | 99.63 | 1 |
| 19F | 100 | 1/2 |
| 31P | 100 | 1/2 |
