3. Introduction to NMR (Nuclear Magnetic Resonance)  


NMR Spectroscopy relies on a being able to exploit the spin property of hydrogen proton which naturally have a quantum spin number of 1/2.  

NMR spectrometer applies a powerful external magnetic field that forces each of hydrogen proton nuclei into one of two of their spin states +1/2 or -1/2.

When the nuclei are placed in the magnetic field, the nuclei is able to absorb and re-emit a photon with a specific radio-frequency of ν .

This re-emitted radio-frequency signal which is called the Free-Induction-Decay (FID), is collected and examined by a separate receiving coil.

FID depends to a large extent on the chemical environment of the proton-containing material. FID from solid material decays very fast whereas that of liquid has much longer duration.

The HMR20 exploits this decay-time-difference to measure the ratios of different phase states of samples, for example, Oil and Water in Seeds.
