Abstract: The Infrared spectra(220-3500 cm-1)and Raman spectra(100-1700 cm-1)of te-tra(p-nitrophenyl)porphyrin and its Cr(Ⅲ),Mn(Ⅲ),Fe(Ⅲ),Co(Ⅱ),Ni(Ⅱ),Cu(Ⅱ)and Zn(Ⅱ)complexes were measured and investigated respectively.The band at 3321 cm-1 and 988 cm-1 belonging to N-Hvibrations of pyrrole disappears when the complex formed.The metal sensitive bands were found at ~1600,~1582,~1547,~1284,~1190,~355 and ~245 cm-1.The bands at 355 and 245 cm-1 of the complexes decrease in wave number in the order of Ni(Ⅱ)>Co(Ⅱ)>Cu(Ⅱ)>Zn(Ⅱ).The bands at ~3110,~1600,~1520,~1350,~850 and ~825 cm-1 resulted from p-nitrobenzene of the porphyrin.
