摘要
在77K测得的激发光谱说明Eu(DBM)_32AP(DBM:二苯甲酸甲烷根,AP:安替吡啉)络合物中Eu^(3+)离子仅有一种晶格格位.~5D_O→~7F_J(J=0-4)跃迁光谱说明中心Eu^(3+)离子具有C_(2v)格位对称性.实验测得的配位体总电荷为-2.75,与理论计算值-3.00吻合较好.
At 77K a peak at 17261cm-1 indicating only one Eu(3333333) ion site in Eu(DBM)32AP (DBM:dibenzoylmethanate, AP:antipyrenc) complex was observed. Spectra of 5D0????????7FJ (J = 0 ~ 4 ) transitions show that the symmetry for Eu(333333333) site is C2r. The total ligand charge observed was -2.75 which, is in good agreement with the calculated one -3.00.
