摘要: Abstract The 19F NMR spectroscopy of several fluorinated β-diketonates U(IV), where the ligand chosen is asymmetrical, has been studied as a function temperature. complexes are U(FOD)4, U(TFBA)4 and U(TFAA)4. Intramolecular motions observed their freezing occurs near −90°C. data in agreement with those 1H NMR.
