Abstract: The FT-IR Spectra of eighteen (R-Cp)2M(NCS)2 were measured. The M-Cp, M-NCS(M=Ti, Zr, Hf) and other vibration modes were reasonably assigned. All complexes of (R-Cp)2M(NCS)2 determined at this paper are bonded by N-M. The influence of the center metal atoms and the substituent on cyclopentadienyl upon the spectra was discussed. It is mainly in far IR. region that center metal atoms influence upon the IR. spectra. The influence of the substituent on cyclopentadienyling upon its vibration is not significant.
