Abstract: The Fourier transform infrared photoacoustic spectra of tetra-(p-nitrophenyl) porphyrin and its Cr(Ⅲ), Mn(Ⅲ), Fe(Ⅲ) Co(Ⅱ),Ni(Ⅱ), Cu(Ⅱ) and Zn(Ⅱ) complexes in the range of 3500—225 cm-1 were measured and investigated.The bands at 3324 cm-1 and 968 cm-1 are N-Hvibrations of pyrrole.The bands at 986 cm-1, 799 cm-1, 737 cm-1 and 629 cm-1 are the vibrations of porphyrin ring.The bands at ~3109, ~1600, ~1520,~1350, ~850, ~825 and ~744 cm-1 result from p-nitrobenzene of the porphyrin.Metal sensitive bands were found at ~1489, ~1076, ~737 and ~245 cm-1.
