title: Transition metal NMR chemical shifts and polarizability effect in organometallic complexes.
abstract: The literature data on substituent influence on the (51)V, (55)Mn, (57)Fe, (59)Co, (61)Ni, (95)Mo, (103)Rh, (183)W, (187)Os and (195)Pt NMR chemical shifts (delta) and on J (M, P; M = Mn, Fe, Mo, Rh, W, Os) coupling constants have been analyzed for 30 series of the organometallic complexes. It has been established for the first time that the delta and J values depend on the inductive, resonance and polarizability effects of substituents. The polarizability effect is caused by the partial charge on the central M atom. The contribution of this effect ranges from 3 to 86%.
