 Title    Sheng  
 Abstract    The structure and properties of a 1.791 molal aqueous LiF solution is investigated by performing molecular dynamics simulations using a water model with both bond flexibility and instantaneously responsive polarization. On average, each cation is in close contact with about one anion. This causes a strong overlap of the hydration shells and an almost complete breakdown of the surround­ ing water structure. While the lone pairs of the hydration waters in the first Li+ shell occupy preferentially tetrahedral positions, the orientational distribution of the solvent molecules around F~ is quite uniform. By comparing various autocorrelation functions of water molecules in the solution and in the pure liquid, the influence of solvated ions on the translational, rotational and vibrational motions of hydration water can be studied.

 Title    Ionenpaare von o-Semichinonen mit Diorganothallium(QI)-Kationen* Ion Pairs of Semiquinones with Diorgano Thallium (III) Cations  
 Abstract    Diorgano thallium hydroxide reacts very smoothly in organic solvents with catechols to stable paramagnetic ion pairs. This reaction has been investigated with two semiquinone anions and 13 different diorgano thallium cations. The data obtained indicate a strong dependence of the thallium coupling constant on the nature of the metal substituents. The effects observed are discussed in terms of electronic and steric interactions. All ion pairs indicate remarkable temperature dependence of the thallium splitting and the g-factor. These results are compared with the results obtained in alkali metal ion pairs using a model described in the literature. Einführung
