Abstract: The infrared and Raman spectra of 11 lanthanide acetylacetonate -a, β, γ, δ- tetraphenylporphyrin complexes LnTPPacac (Ln. lanthanide elements, TPP. tetraphenylporphyrin, acac: acetylacetone)in the region 200-4000cm^-1 and 100-4000cm^-1 have been measured respectively.Because of the coordinate bonding between the rare earth ion and nitrogen in TPPforms, the band near 400cm^-1, M-Ostretching vibration on the acetylacetonate ring, becomes weaker, this band is shifted to the lower wavenumber, and it is sensitive to a change in rare earth ion and its frequency changes periodically with the atomic number and total angular quantum numbers of the rare ion, showing the "tetra effect" and "inclined Weffect" characteristic of lanthanides.The band near 984cm^-1, the C-H rocking vibration in pyrrole also shows mentioned above laws.The band 3317cm^-1, N-Hstretching vibration, disappears upon complex formation, the vibration coupling between the M-Nstretching and the ring deformation appears.
