摘要：

Examples of carbon-13 NMR spectra exhibiting CIDNP during pulse radiolysis of aqueous solutions of simple organic and inorganic compounds in D2O 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 The following aspects of carbon-13 CIDNP are illustrated: (A) detection of CIDNP in a reaction where all protons have been replaced by deuterons, (B) generation of a theoretically ideal radical pair with only one I = 1/2 nucleus, (C) use of isotopic enrichment to distinguish two different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 systms studied include the radiolysis of CD3OD in D2O (D· and ·CD2OD radicals) and the radiolysis of sodium formate in D2O (CO2-· radical), sodium carbonate (CO3-·), and sodium chloroacetate (·CH2COO-). © 1979 American Chemical Society.
