Chemical shifts occurring in carbon-13 magnetic resonance spectroscopy are utilized to assess the site of complexation of nucleosides to enPdC12 in neutral aqueous solutions. Binding occurs at N3 in cytidine, thymidine, and uridien, at N7 in 1-methylguanosine, and at N1 in guanosine. For most carbon
## Abstract The addition of Co^2+^ to D~2~O solutions of Nicotinamide Adenine Dinucleotide induces modifications of the ^13^C n.m.r. signal line widths of these coenzymes. Analysis of the observed paramagnetic effects shows that both states (reduced and oxidized) and both conformations (folded or u
