In this study we investigate the effects of geometry, exchange-correlation functional, solvent, and scalar-relativistic and spin-orbit corrections on the nuclear magnetic shielding - mainly for 13C and 15N atoms connected to a heavy-atom center. The 13C and 15N NMR chemical shifts are found to be best reproduced by using a B3LYP or PBE0 approach with 30 % and 40-50 % exact-exchange admixtures for the Pt2+ and Au3+ complexes, respectively.
