question

The 99Ru chemical shift of [Ru(H2O)6]2+ is 16,050 ppm relative to [Ru(CN)6]2- at 0 ppm. The electronic excitation energies of [Ru(H2O)6]2+, [Ru(CN)6]2- and [Ru(NH3)6]2+ are 18,900, 40,000 and 25,600 cm-1 respectively. Assuming that the chemical shift differences are dominated by paramagnetic currents, determine the chemical shift of [Ru(NH3)6]2+.

choices

  1. 7,530 ppm
  2. 8,090 ppm
  3. 11,070 ppm
  4. 14,840 ppm
