摘　　要：研究了四(对-硝基)苯基卟啉及其Cr(Ⅲ)、Mn(Ⅲ)、Fe(Ⅲ)、Co(Ⅱ)、Ni(I)、Cu(Ⅱ)、Zn(Ⅱ)配合物的3500-225 cm-1范围的傅立叶变换红外光声光谱.对主要谱带进行经验归属.金属敏感谱带出现在-1489、-1076、-737和-250 cm-1等附近.-250 cm-1谱带是M—N伸缩振动和卟啉环变形的复合振动.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-H vibrations 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.
