  Existence of cooperative absorption lines for Yb–(OH,OD) pairs: Absolute oscillator strengths

  摘要：

  Due to its energy scheme simplicity, Yb3+ has been chosen in order to investigate the (Ln3+OH−) cooperative pair lines predicted by Dexter. For the first time by direct absorption such pair lines have been shown to exist in Yb(OH3),Yb(OOH) microcrystals and in [Yb(C2H5SO4),9H2O],[YbCl3,6H2O] crystals and in their aqueous solutions, either with light or heavy water. Absolute oscillator strengths of pairs at sum frequencies of the Yb electronic line (2F7/2−2F5/2) and of the ν1 stretching (OH)−, (OD)− vibrations have been found to be respectively (3.5±0.5)×10−9 and (2.6±0.3)×10−9. Results are discussed in terms of the cooperative model of Stavola–Dexter and of the vibronic sideband description, showing what is common to both models and what is different.

  [Ln(H2O)9] (C2H5SO4)3 (Ln = La-Lu) complexes have been measured and the peak at 316 (La)342 (Lu) cm−1 assigned to a νM-O vibrational mode. Its frequency shows a continuous increase with decrease in the ionic radius of Ln3+. We interpret the results as evidence for the hydration number change of Ln3+ ions in the intermediate region of the rare earth series in aqueous rare earth electrolyte solutions.

  测量了[Ln（H 2 O）9 ]（C 2 H 5 SO 4）3（Ln = La-Lu）配合物的远红外光谱，并且在316（La）342（Lu）cm -1处具有峰分配给νM -O振动模式。随着Ln 3+离子半径的减小，其频率不断增加。我们将结果解释为稀土水溶液电解质溶液中稀土系列中间区域中Ln 3+离子水合数变化的证据。
