    Description / Table of Contents: Zusammenfassung Es wurden die Komplexierungsgeschwindigkeiten von In3+ und Ga3+ in Lösungsmittelsystemen mit Salzsäure, Schwefelsäure oder Salpetersäure und verschiedenen organischen Lösungsmitteln gemessen. Dabei konnte gezeigt werden, daß die Geschwindigkeit in wäßrig-saurem Medium (ohne Zusätzen von organischen Verbindungen) und dann fast immer in den ersten Minuten der Reaktion am größten ist.
    Notes: Summary The rate and the rate constant of the process of complexing of In3+ and Ga3+ were evaluated in media containing hydrochloric acid, sulfuric acid or nitric acid and different organic solvents. It was established that the rate of the process is maximum in aqueous-acid environments (without presence of organic additions), in almost all investigated cases in the first minutes of the reaction.

    Notes: The relations of quantum and kinetic isotope effects are investigated using the exact quantum corrections to the collision and activated complex theories. The latter are computed for the collinear three-atomic reaction H2 + H → H + H2 and the related isotopic reactions using realistic potential energy surfaces. Taking into account the bent configurations of the collision complex H-H-H gives a very good agreement between the quantum collision theory and the experimental data for the absolute values and the isotopic ratios of rate constants. Classical trajectory calculations yield considerably lower results.
