Chapter 13 NMR Spectroscopy - Chapter 13 NMR Spectroscopy NMR - Nuclear Magnetic Resonance NMR is a form of spectroscopy that uses an instrument with a powerful magnet to analyze organic compounds. And also Labeling studies in biochemistry. When an external magnetic field is applied, the spin shifts to precessional orbit with a precessional frequency. It is a research technique that exploits the magnetic properties of certain atomic nuclei. It involve information about NMR Spectroscopy ( a spectroscopic techniques), factors influencing , proton NMR and their applications of NMR as well as Nuclear magnetic imaging. The NMR behaviour of 1 H and 13 C nuclei has been exploited by organic chemist since they provide valuable information that can be used to deduce the structure of organic compounds.

Zeeman first observed the strange behavior of certain nuclei when subjected to a strong magnetic field at the end of the nineteenth century, but the practical use of the so-called “Zeeman effect”was only made in the 1950s when NMR spectrometers became commercially available. 115Sn is much less sensitive than either 117Sn or 119Sn. Afsath.B It determines the physical and chemical properties of atoms or the molecules in which they are contained. 5. They all yield narrow signals over a very wide chemical shift range.
