Abstract: The Fourier Transform infrared photoacoustic spectra of tetra-(para-hydro-xyphenyl) porphyrin and its Cr(III), Mn(III), Fe(III), Co(II), Ni (II), Cu (II) and Zn(II) complexes in the range 3700-200cm-1 were measured and investigated. There exist intermolecular hydrogen bonds in the porphyrin and its complexes. The vibration coupling between the M-Nstretching and the porphyrin ring deformation appears at 250cm-1. The band at 316cm-1 is stretching vibration of M(III)-Cl. Metal sensitive bands were found at about 1550, 1350, 1076, 1000 and 250cm-1.
