摘要： 研究乙酰丙酮-meso-四-(对-氯代)苯基卟啉及其Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Lu配合物在3600～220cm-1范围内的傅立叶变换红外光声光谱,对其主要谱带进行经验归属。实验结果表明,四-(对-氯代)苯基卟啉与稀土乙酰丙酮配合物中的金属离子配位,削弱乙酰丙酮环上的M-O键伸缩振动,使该谱带向低波数方向移动。金属敏感带出现在～1558、～1474、～1427、～1219、～798、～733、～250cm-1.

Abstract: The fourrier transform infrared photoacoustic spectra of tetra-(parachlorophenyl)porphyrin and its coordination compounds LnT(p-Cl)PPacac(Ln:Nd,Sm,Eu Gd,Tb,Dy,Ho,Er,Lu)in the range of 3600-220 cm-1were measured and investigated. Because of the coordination bonding between the rare earth ion and nitrogen in LnT(p-Cl)PPacac forms,the band near 400 cm-1and M-O stretching vibration on the acetylacetonate ring become weaker,and shifted to the lower wavenumber. Metal sensitive bands were found at about 1558,1474,1427,1219,798,733 and 250 cm-1.
