Cavanagh, Fairbrother, Palmer, and Skelton Protein NMR spectroscopy Principles and practice Academic press, 1996. 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. The radar technology developed during World War II made many of the electronic aspects of the NMR spectrometer 1H and 13C are the most important NMR active nuclei in organic chemistry Natural Abundance 1H 99.9% 13C 1.1% It involve information about NMR Spectroscopy ( a spectroscopic techniques), factors influencing , proton NMR and their applications of NMR as well as Nuclear magnetic imaging. NMR is a very powerful technique that enables the study of physicochemical, electronic, and structural properties of molecules, looking at the quantum mechanical magnetic properties of an atomic nucleus (specifically, the chemical shift and Zeeman effect on the resonant frequency), in solution as well as the solid state.
