摘　　要：The NMR and FT\|IR Spectra of ten (ηC 6H\-9CRR′ Cp)\-2MCl\-2 (M=Ti,Zr) were measured.The constructions of the compounds were identified by 1H NMR and 13 C NMR spectra.All complexes are bonded by M\|Cp through center of Cp.The vibration modes were reasonably assigned,absorption of ν s M\|Cp (A\-1) (M=Ti and Zr) vibration all appear in 310?cm -1 or so,while ν as M\|Cp (B) appear around 410?cm -1 and 360?cm -1 for Ti and Zr respectively.The influence of the center metal atoms and the substituents upon the NMR and FT\|IR spectra were discussed.The NMR and FT\|IR Spectra of ten (ηC 6H\-9CRR′ Cp)\-2MCl\-2 (M=Ti,Zr) were measured.The constructions of the compounds were identified by 1H NMR and 13 C NMR spectra.All complexes are bonded by M\|Cp through center of Cp.The vibration modes were reasonably assigned,absorption of ν s M\|Cp (A\-1) (M=Ti and Zr) vibration all appear in 310?cm -1 or so,while ν as M\|Cp (B) appear around 410?cm -1 and 360?cm -1 for Ti and Zr respectively.The influence of the center metal atoms and the substituents upon the NMR and FT\|IR spectra were discussed.
