Matching of the frequency of a precessing nucleus with a radio wave frequency is termed:

Question

Quizplus · Accepted Answer

Resonance occurs when the frequency of electromagnetic radiation matches the frequency of precession of the nucleus. This leads to maximum absorption and emission of energy and is the basis of magnetic resonance imaging (MRI). Precession refers to the spinning motion of the nucleus, relaxation refers to the process by which the precession returns to equilibrium after excitation, and magnetization refers to the alignment of nuclear spins in a magnetic field.
