The NMR and FT-IR spectra of 10 (eta C6H9CRR'-Cp)(2)MCl2 (M=Ti, Zr) were measured. Results indicate that the metal atom formed bond combination with the center of cyclopentadienyl. NMR spectra move to high field when electronegativity decreases. The electronegativity difference of Ti and Zr mainly influences their IR spectra at the far-infrared range. The characteristic vibrational frequencies of the compounds move to low wave number region with the lower electronegativity. The difference of substituents imposes little effect on the compounds' vibrational frequencies.
