Answer» Chemical Exchange Effects in NMR Chemical exchange, in NMR terms, means that a nucleus moves among a set of magnetic environments. The sample is macroscopically at equilibrium, but an individual nucleus exchanges among a number of sites, so the magnetic properties of the nucleus are modulated by the exchange. Decomposition, the opposite of combination, involves the breakdown of a single substance into two or more different substances. The signs ofchemical changeincludechangesin color, temperature, the production of light,changesin odor, and the formation of gases.
