Abstract: The fourier transform infrared photoacoustic spectra of tetra-(para octanoyloxyphenyl) porphyrin T(p-OO)PPH2 and its Mn(Ⅲ), Fe(Ⅲ), Co(Ⅱ), Ni(Ⅱ), Cu(Ⅱ) and Zn(Ⅱ) complexes in the range of 3600~190 cm-1 were measured and investigated. The bands at 3318.0 and 968.0 cm-1 of T(p-OO)PPH2 are due to the N—Hstretching and in plane and out-plane bending vibration of the pyrrole groups. All these bands disappear upon complexes formation. The vibration coupling between the M—N stretching and the porphyrin ring deformation appears at 243 cm-1. Metal sensitive bands were found at 1504, 1350, 1022, 995, 796 and 235 cm-1.
