Nuclear magnetic resonance nondestructive nature

Infrared, ultraviolet, and nuclear magnetic resonance spectroscopies differ from mass spectrometry in that they are nondestructive and involve the interaction of molecules with electromagnetic energy rather than with an ionizing source. Before beginning a study of these techniques, however, let s briefly review the nature of radiant energy and the electromagnetic spectrum. 

Pulsed nuclear magnetic resonance (NMR) has been used for such analyses due to the speed, repeatability, and nondestructive nature of the measurement. Additionally, the method requires no solvents, an important consideration for environment friendliness. Modern benchtop NMR systems are highly automated and computerized, which allows unskilled personnel to be trained to run the measurements. 

High-resolution nuclear magnetic resonance (NMR) spectroscopy is a relatively rapid technique and is highly robust in terms of reproducibility of results. The ubiquity of protons in cellular metabolites and the fact that other nuclei are observable by NMR (e.g., and mean that a relatively large number of different metabolites can be detected. Furthermore, the technique requires minimal sample preparation, and its nondestructive nature allows for more analyses to be...
