NMR Spectroscopy and its Principle

Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique utilised in quality control and research for evaluating the content and purity of a sample as well as its molecular structure. For example, nuclear magnetic resonances are used for quality analysis of mixtures containing known compounds. The resonant frequencies of the nuclei are then estimate and converted into an NMR spectrum that shows all of the right frequencies as peaks on a graph. The principle of NMR is that have nuclei have spin and all nuclei are having charge. If an magnetic field is applied, an energy transfer is possible between the base energy to a higher energy level.
