Electrons can spin. In a similar way, all nuclei can spin (except those with an even atomic number and an even mass number). These positively charged spheres behave like magnets. When placed into a strong magnetic field, each nucleus can either align with the external magnetic field or against it. The lower energy state occurs when the nucleus is spinning in alignment with the magnetic field, and the high energy state occurs when the nucleus is spinning out of alignment with the magnetic field Given sufficient energy, the nuclei can ‘flip’ between the two states. In an NMR spectrometer, the magnetic field strength can be varied. The magnetic field strength at which the nucleus flips can thus be measured. The strength of magnetic field at which a particular nucleus flips is dependant upon the environment of that nucleus.

We say that these show different chemical shifts - ie they flip at different field strengths. The observed chemical shift is measured against a standard - usually tetramethylsilane (TMS). The example above shows methanol. Methanol has three H nuclei which have an identical environment (labelled 1) and one hydrogen in a different environnment (labelled 2). Two peaks due to methanol can be observed. The smallest is due to the hydrogen labelled 1. The second is due to the three other hydrogens. It is three times the size of the first.
