    Notes: Abstract The themodynamic properties of solutions of deuterium chloride (DCl) in deuterium oxide (D2O) have been determined from emf measurements of the electrochemical cell without transference from 5 to 50°C, and from 0.002 to 1.0 mol-kg−1. The standard potential of the silver/silver chloride electrode relative to the platinum/deuterium electrode has been determined. An equation for the Gibbs energy as a function of temperature has been derived from which the enthalpy, entropy, and heat capacity have been computed. Equations for the activity coefficient and the osmotic coefficient of DCl in D2O have been developed. The excess Gibbs energy of the solution and the excess partial molar free energy as a function of temperature have been calculated, from which the other excess thermodynamic properties have been computed. The values for the heat capacity and the apparent molar heat capacity have been compared with calorimetric data in the literature. The relative partial molar enthalpy has been calculated. The solvent isotope effect on the excess thermodynamic functions is discussed.

    Description / Table of Contents: Zusammenfassung In der vorliegenden Arbeit wird nach kurzer Diskussion der Vorgeschichte und der Grundlagen ein Programmsystem für Personal-Computer vorgestellt, welches den Aufbau eines laborspezifischen Datenbank-bzw. Informationssystems erlaubt und gleichzeitig aufgrund seiner standardisierten Programm- und Datenstrukturen und der Kompatibilität zu bzw. Portabilität auf verschiedenen Hardwaresystemen die Grundlage zu einer nationalen und internationalen Zusammenarbeit von gleichartig interessierten Fachkollegen bietet.
    Notes: Summary After a short description of the background and fundamentals, a program system for a microcomputer is described that permits the implementation of a laboratory-specific database and information system. Due to standardized program and data structures and compatibility with different hardware, as well as portability, similar laboratories have the potential of carrying out cooperative studies on a national and international basis.
