THE VIBRATIONAL SPECTRA OF ORGANOMETALLIC COMPOUNDS (II) FT-INFRARED, LASER RAMAN SPECTRA AND NORMAL COORDINATE CALCULATION FOR 1,1'-DIMETHYLFERROCENE

FT-IR and Raman spectra of (CH3Cp)(2)Fe have been measured. On the basis of qualitative assignment the force constants ([1]) of Cp2M(M = Mn, Fe, Rn) obtained by C F matrix have been translated to the molecule of (CH3Cp)2Fe, only the metal coordinate force constants have been adjusted. The same method of C F matrix has been used for calculating the vibrational spectra frequencies of (CH3Cp)2Fe, the result is consistent with the observal one.
