- 論文の詳細を見る
Equilibrium constants, enthalpies, and entropies of formation of the shift reagent-substrate adducts were determined by the measurement of infrared spectra. Aniline was employed as substrate in most cases since its NH stretching absorption bands (ν<SUB>as</SUB>) does not overlap with those of the adducts and suitable to estimate the amount of its free species quantitatively. A series of Ln(dpm)<SUP>3</SUP> and Ln(fod)<SUP>3</SUP> (where Ln=Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, and Yb) were used as shift reagents. The formation constants (<I>K</I><SUB>1</SUB> and <I>K</I><SUB>2</SUB>), as well as <I>ΔH</I>, decrease in the increasing order of the atomic numbers of the central lanthanoid ions. The results were compared with those on some bis(β-diketonato) complexes of transition metal ions and discussed.
