Introduction：

Nuclear magnetic resonance (NMR) spectrometry is basically another form of absorption spectrometry,

akin to IR or UV spectrometry. Under appropriate conditions in a magnetic field, a sample can absorb electromagnetic

radiation in the radio frequency (rf) region at frequencies governed by the characteristics of the sample.

Absorption is a function of certain nuclei in the molecule. A plot of the frequencies of the absorption peaks

versus peak intensities constitutes an NMR spectrum. 

Function（application）：

NMR spectroscopy is a powerful technology for structures elucidation of natural product, medicine, organic compound, inorganic complex and polymer.
