magnetic resonance
Nuclear spin response
Magnetic resonance is the absorption of energy by atomic nuclei in a magnetic field when exposed to electromagnetic radiation at specific frequencies.
The phenomenon underlies MRI (magnetic resonance imaging), which produces detailed images of soft tissues without radiation: The MRI revealed a torn ligament.
Nuclear magnetic resonance (NMR) spectroscopy uses the same principle to analyze molecular structures in chemistry.
