✦ Synopsis


An overview is given of the recent development and use of Ž . density functional methods in nuclear magnetic resonance NMR chemical-shift Ž . calculations. The available density functional theory DFT methods are discussed, and examples for their validation and application are given. Relativistic effects are also considered, with an emphasis on spin᎐orbit coupling. The systems discussed range from transition-metal complexes and clusters via biological systems and fullerenes to weakly bound van der Waals molecules. DFT results not published previously comprise spin᎐orbit effects on 31 P chemical shifts in phosphorus halides, the orientation of the 31 P-shift tensor in Ž .Ž . Ž 95 . 13 Ru PPh CO , ␦ Mo data, C and endohedral chemical shifts for fullerenes 4 1 3 and for C H , as well as the shielding surface of the Ne molecule. ᮊ

A previous model for the calculation of proton chemical shifts in substituted alkanes based upon partial atomic charges and steric interactions has been modiÐed by the replacement of the CÈC bond anisotropy term with an orientation-dependent c e †ect (i.e. C É C É C É H). The new scheme (CHARGE5) pr
