Abstract
Proton-decoupled natural-abundance carbon-13 Fourier transform n.m.r. spectra of aqueous solutions of aquocyanocobyric acid and dicyanocobyric acid were recorded at 15·08 MHz: the spectrum of the first compound showed the presence of two isomers, and many of the carbon atoms showed large chemical shift variations between the two isomers.
