Nuclear magnetic resonance method

Analytical method for obtaining molecular structure information of compounds by studying the absorption of radio frequency radiation by atomic nuclei in strong magnetic fields

Nuclear magnetic resonance spectroscopy It is an analytical method to study the absorption of radio frequency radiation by atomic nuclei in a strong magnetic field, so as to obtain information about the molecular structure of compounds.

Chinese name: Nuclear magnetic resonance method
Definition: To study the absorption of radio frequency radiation by atomic nuclei in a strong magnetic field, so as to obtain analytical methods for molecular structure information of compounds

The spectrum obtained by taking 1H core as the research object is called hydrogen nuclear magnetic resonance spectrum; The spectrum obtained by taking 13C core as the research object is called carbon nuclear magnetic resonance spectrum. Nuclear magnetic resonance spectrum And Infrared absorption spectrum With strong complementarity, it has become one of the powerful tools for structural analysis of organic and inorganic compounds. In recent years, the nuclear magnetic resonance spectrum analysis technology has developed rapidly two-dimensional And three-dimensional nuclear magnetic resonance pulse Fourier transform nuclear magnetic resonance and other technologies are increasingly widely used.
