Abstract Fourier transform NMR studies of 17O, 35Cl, 51V, 53Cr, 55Mn and 95Mo are reported for aqueous solutions of the oxyanions ClO4 -, VO4 3-, CrO4 2-, MnO4 -, and MoO4 2-, partly enriched in 17O. The indirect spin-spin coupling constant between 17O and the quadrupolar central nucleus is determined: A linear dependence of the reduced coupling constants on the atomic number of the central nucleus in the isoelectronic series VO4 3-, CrO4 2- and MnO4 - was found.
