This is not my best topic so this may contain inaccuracies but from what I remember...

A nucleus with an odd number of nucleons spins and behaves like a bar magnet. In NMR a magnetic field is applied this causes all the nuclei to all flip to the same high energy state (so all the magnets are facing the same direction). As this makes them unstable they flip back when you use radio waves - the frequency of radio waves needed is measured.
