Abstract
A new synthesis of trisfluoroacetylactone (TFA) and hexafluoroacetylac tone (HFA) Nd complexes: Nd(TFA)(3) . 2 H2O and Hd(HFA)(3) . 2 H2O is reported. The photoacoustic (PA) spectra in the 300-800 nm region of t he compounds NdCl3 . 6H(2)O, Nd(TFA)(3) . 2H(2)O and Nd(HFA)(3) . 2H(2 )O are reported. The PA absorption bands are assigned and their relati ve intensities represented by intensity branching vectors are calculat ed. The perturbation of the ligand on the energy levels of Nd3+ ion is discussed and a model of the relaxation process of Nd(HFA)(3) . 2H(2) O is proposed based on its PA and absorption spectra.
