The ^1H-^1H TOCSY and ^1H-^1H NOESY were used to study the strucures of a series of substitutedindenyl titanium and zirconium complexes. It is found that there is nuclear Overhauser effect between he hydrogens of the two independent indenyl ligands in the sandwich complexes, which provides efficient evidences for the determination of the relative steric structure of the two indenyl ligands. Thus we suggest that the ^1H-^1H NOESY dimension spectra could be an effective method to investigate the steric structures of the metallocene complexes.
