Abstract: The fourrier transform infrared photoacoustic spectra of tetra-(parachlorophenyl)porphyrin and its coordination compounds LnT(p-Cl)PPacac(Ln:Nd,Sm,Eu Gd,Tb,Dy,Ho,Er,Lu)in the range of 3600-220 cm-1were measured and investigated. Because of the coordination bonding between the rare earth ion and nitrogen in LnT(p-Cl)PPacac forms,the band near 400 cm-1and M-O stretching vibration on the acetylacetonate ring become weaker,and shifted to the lower wavenumber. Metal sensitive bands were found at about 1558,1474,1427,1219,798,733 and 250 cm-1.
