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3500~225cm-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~250cm-1等附近.~250cm-1谱带是M—N伸缩振动和卟啉环变形的复合振动.

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.
