Abstract
CIDNP allows selective NMR signal enhancement of aromatics, aldehydes, ketones, alcohols, amines, olefines, etc. via heat or photoexcitation of certain reagent systems. The CIDNP typically stems from radical pairs, but occasionally from triplets via the Overhauser Triplet Mechanism (quinones). The latter may act intermolecularly, in which case nonselective enhancement is possible.
