THE VIBRATIONAL SPECTRA OF LANTHANIDE THENOYLTRIFLUOROACETONATE COMPOUNDS
Abstract:
The FT-IR and Raman spectra for (TTA)_4LnQH(Q=quinoline) series were measured and discussed as following:
1. Structure and spectra
Due to the similar IR and Raman spectra observed for (TTA)_4LnQHseries there would be the structural analogy for the compounds, i.c. the central ion Ln~(3+) is coordinated with eight oxygen atoms which belong to four TTA groups respective- ly. IR spectra indicates that The hydrogen bond between the nitrogen of quinoline and the oxygen atom of TTA group is formed to make a stable molecular system.
The facts that there is a successive change of Ln-O IR(303-320 cm~(-1)) and Raman (310-323 cm~(-1)) vibrational frequencies with the increase of lanthanide atomic number and the vibrational frequencies of TTA C=O groups coordinated come down to near 1605 cm~(-1) from near 1657 cm~(-1) indicats the existance of hydrogen bond. In addition the low frequency spectra (500-100 cm~(-1)) is discussed in detail.
2. The abnormal spectra of Tb and Tm
