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.
In particle physics, proton decay is a hypothetical form of radioactive decay in which the proton decays into lighter subatomic particles, such as a neutral pion and a positron.There is currently no experimental evidence that proton decay occurs.In the Standard Model, protons, a type of baryon, are theoretically stable because baryon number (quark number) is conserved (under normal circumstances; however, see chiral anomaly).or the type of radioactive decay in which a nucleus ejects a proton, see Proton emission. The pattern of weak isospins, weak hypercharges, and color charges for particles in the GeorgiâGlashow model.
