Nuclear reaction Common light particles are often abbreviated in this shorthand, typically p for proton, n for neutron, d for deuteron, α representing an alpha particle or helium-4, β for beta particle or electron, γ for gamma photon, etc. The reaction above would be written as Li-6(d,α)α. In 1919, Ernest Rutherford was able to accomplish transmutation of nitrogen into oxygen at the University of Manchester, using alpha particles directed at nitrogen N + α → O + p. This was the first observation of an induced nuclear reaction, that is, a reaction in which particles from one decay are used to transform
Nitrogen-15 nuclear magnetic resonance spectroscopy Nitrogen-15 nuclear magnetic resonance spectroscopy Nitrogen-15 nuclear magnetic resonance spectroscopy (nitrogen-15 NMR spectroscopy, or just simply N NMR) is a version of nuclear magnetic resonance spectroscopy that examines samples containing the N nucleus. N NMR differs in several ways from the more common C and H NMR. To lift the restraint of spin 1 found in N, N NMR is employed in samples for detection since it has a ground-state spin of ½. SinceN is 99.64% abundant, incorporation of N into samples often requires novel synthetic techniques. Two sources of nitrogen-15 are the positron emission of oxygen-15 and the beta
