• Pulsed neutron diffraction study on the structures of glassy ⁷LiX–KX–CsX–BaX₂ (X=Cl, Br, and I)

  The structures of glassy 7LiX–KX–CsX–BaX2 (X=Cl, Br, and I) have been investigated by means of pulsed neutron diffraction experiment. The obtained total radial distribution functions were discussed with the help of the molecular dynamics simulation based on the Tosi–Fumi potential. The Li–X (X=Cl, Br, and I) distances in the three glasses are 2.37, 2.49, and 2.70 Å, respectively, which are 0.2–0.3 Å shorter than those in the rocksalt-type LiX crystals. For each system, it is found that the coordination number of the X− ions around the Li+ ions is about four when only the closely contacting X− ions are counted. Because of the 1:1 monovalent character of the present systems, the first coordination shell around the Li+ ions has the ill-defined outer extent, compared with the 4:2 and 2:1 charged systems such as SiO2 and ZnCl2. This causes the increase of the coordination number, from four to six, when all the near-neighbor X− ions are counted as the surrounding ions.

  Time-of-Flight (TOF) neutron diffraction measurements were carried out for 12 mol% *HCOO7Li solutions in D2O. The H/D isotopic substitution technique was applied to the formyl-hydrogen atom of the formate ion in order to determine both the hydration structure around the formyl-hydrogen atom and the intramolecular structure of HCOO− in the aqueous solution. The hydration structure around the formyl-hydrogen atom was analyzed by applying a least-squares refinement procedure to the observed intermolecular difference function. The intramolecular distances within the formate ion were determined to be r(Hf–C) = 1.072(2) Å and r(Hf···Of) = 2.015(8) Å.

  对 D2O 中 12 mol% *HCOO7Li 溶液进行了飞行时间（TOF）中子衍射测量。对甲酸根离子的甲酰基氢原子采用了 H/D 同位素置换技术，以确定水溶液中甲酰基氢原子周围的水合结构和 HCOO- 的分子内结构。甲酰基氢原子周围的水合结构是通过对观测到的分子间差分函数应用最小二乘精化程序进行分析的。甲酸根离子的分子内距离被确定为 r(Hf-C) = 1.072(2) Å 和 r(Hf---Of) = 2.015(8) Å。
