研究了六亚甲基桥连的希夫碱及其锰(Ⅲ)络合物催化剂的红外光谱,对一些主要谱带进行了经验归属.配体的分子内氢键谱带出现在~3438CM－1(以LH为例),νC＝N谱带在~1630CM－1(以CH为例,下同),苯的特征谱带在~1598,~1469和~755CM－1,νMN?N为主的复合振动在~369CM－1,δMN?N为主的复合振动在~247CM－1,νMN?O为主的复合振动在~329CM－1,δMN?O为主的复合振动在~275CM－1,νMN?CL特征谱带在~303CM－1.与苯基锰(Ⅲ)卟啉络合物相比,νMN?N特征谱带向高波数位移,νMN?CL特征谱带则向低波数有较大位移.“,”The FTIR spectra(3800～150cm??-1?)of Schiff base ligands and Mn(Ⅲ)complexes with methylene bridge were measured and investigated.The major bands have been empirically assigned in comparison with a large number of previous results.The characteristic absorption bands of intra?molecular hydrogen bond of ligands were found at ?ca?.3438cm??-1?.The ?ν???C=N??? of ligands and complexes were found at ?ca?.1630cm??-1?.The characteristic absorption bands of the phenyl ring of ligands and complexes were found at ?ca.?1...
