Abstract
13C nuclear relaxation rates have been measured for aqueous solutions of imidazole at 31 °C for several values of pH. The influence of Mn(II) and Cu(II) on these relaxation rates has been examined. The results indicate that 13C transverse relaxation rates of imidazole in the presence of these metals are completely dominated by the scalar mechanism. Because of the important influence of this mechanism it is not possible to obtain the geometry of complexes between imidazole-like ligands and Mn(II) or Cu(II) from 13C line-width measurements.Keywords
