This magnetic field makes the possible spin-states of the nucleus differ in energy, and using NMR techniques the spins can be made to create observable transitions between the spin states. Common NMR active nuclei are 1H, 13C, 31P, 15N, 29Si, and many more.wo-dimensional NMR spectra have two frequency axes, which can correspond to like nuclei (i.e. 1H-1H) or different nuclei (i.e. 1H-13C), and a third dimension of peak intensity. More recently, NMR experiments have been developed that contain information in three, four, and even five dimensions.
Uses of NMR spectroscopy. Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and reserach for determining the content and purity of a sample as well as its molecular structure.For example, NMR can quantitatively analyze mixtures containing known compounds.ses of NMR spectroscopy.
