NMR Brief Overview

Nuclear magnetic resonance spectroscopy (NMR) is based on the magnetic properties of certain atomic nuclei. It has become a cornerstone of modem chemical analysis, and is now of major importance in studying 

The magnitude of the nuclear magnetic moment is related to a quantity known as the gyromagnetic ratio (y) (see Table 2.2)  

Q What is the resonant frequency for a proton in a magnetic field of 14.1 Tesla  

Proton NMR is most commof i because of hydrogens natural abundance and large gyromagnetic ratio. Studies with other nuclei such as C and . often require isotopic enrichment of the samples. 

NMR spectrometers are often Classified according to their resonant frequency for protons. For example, a 600 MHz NMR Instrument would comprise a 14 t T magnet in which h nude would resonate at roughly this Irequency. Other nuclei would have different frequencies.
