More classification
Nuclear magnetic resonance (NMR) is a nucleus with magnetic moment not zero. In the field of external magnetic field, the spin energy level is divided into a secant, and resonance absorbs the physical process of a certain frequency of radiofrequency radiation.Nuclear magnetic resonance spectroscopy is a branch of spectroscopy. Its resonance frequency is in the radio frequency band, and the corresponding transition is the nuclear spin transition on the nuclear seaman energy level.
