Examples of carbon-13 NMR spectra exhibiting chemically induced dynamic nuclear polarization (CIDNP) during pulse radiolysis of aqueous solutions of simple organic and inorganic compounds in D/sub 2/O are presented. The following aspects of carbon-13 CIDNP are illustrated: (A) detection of CIDNP in a reaction where all protons have been replaced by deuterons, (B) generation of a theoretically ideal radical pair with only one I = 1/2 nucleus, and (C) use of isotopic enrichment to distinguish two different polarization pathways, and (D) comparison of proton and carbon-13 CIDNP from the same sample. The chemical systems studied include the radiolysis of CD/sub 3/OD in D/sub 2/O (D. and .CD/sub 2/OD radicals) and the radiolysis of sodium formate in D/sub 2/O (CO/sub 2//sup -/.radical), sodium carbonate (CO/sub 3//sup -/.), and sodium chloroacetate (.CH/sub 2/COO/sup -/).
