The effects of Co(acetylacetonate)2, Ni(acetylacetonate)2, and Cu(ethyl acetoacetate)2 on the nuclear magnetic resonance spectra of a variety of alcohols and amines have been studied. Changes are produced in the spectra, which are useful for assigning the signals.

The utility of n.m.r. shift reagents, Eu(DPM)3 and Pr(DPM)3, can be extended to polyfunctional molecules containing acetate and amide groups with significant spectral simplification and definitive peak assignments based on "signal crossover" phenomena.
