Nuclear magnetic resonance is a technique used to detect what chemicals make up a sample containing unknown materials, or proportions of material. The sample is exposed to radio waves, and the frequency of electromagnetic energy that the sample absorbs is recorded. Because different atoms absorb unique frequencies of radiation, it is possible to determine what sort of atoms are present in the sample. NMR is now known as Magnetic Resonance Imaging (MRI).
