✦ Synopsis
The nuclear shielding of (99)Ru in a wide variety of complexes was investigated computationally by DFT methods, including relativistic effects (by means of the Pauli and ZORA approximations), up to spin-orbit coupling and Slater all-electron or frozen-core basis sets. Mononuclear complexes, a trinuclear cluster and a ruthenium-substituted polyoxometalate were included. Chemical shifts calculated in this way correlated very satisfactorily with experimental values, with fit lines having slopes close to unity. In the few cases where a comparison was possible, spin-spin coupling constants involving (99)Ru were also successfully calculated.

The NMR parameters characterizing the spectra of trans- and cis-decalins were determined from theoretical calculations and experimental spectra. The calculated values of the shielding constants are in good agreement with the measured chemical shifts, with a small but noticeable difference in accurac
