## Abstract ^17^O NMR longitudinal and tranverse relaxation rates and chemical shifts were measured at variable temperature at three magnetic fields (1.4, 4.7 and 9.4 T) for aqueous solutions of the complexes [Gd(H~2~O)~8~]^3+^ and [Gd(PDTA)(H~2~O)~2~]^−^. The transverse relaxation rates and chemic
