    Notizen: Abstract Heats of transport of 0.01m (molality) LiCl, NaCl, KCl, RbCl, and CsCl as well as the concentration dependence of the heat of transport of NaCl (up to 1.5m) and KCl (up to 2m) were studied potentiometrically from the measurement of thermoelectric powers of the silver-silver chloride thermocell at a mean temperature of 25°C. Heats of transport of alkaline chlorides were found to be smaller in D2O than in H2O. Effective diffusion coefficients were also found to be smaller. The solvent isotope effect observed is discussed, and possible rationalization is given in terms of solvent properties, structural effects, and motions of ions and solvent molecules.

    Notizen: An asymptotic expansion method has been used to calculate the Morse matrix elements for the vibration-rotation transition. A general expression has been derived for the quartic matrix elements, which can be reduced to the expressions for the cubic, quadratic, and linear matrix elements. The results agree extremely well with those given by the factorization method outlined by Badawi et al., and are similar to those given by Coquant et al., who used quite complicated and lengthy equations based on the Dunham potential. Earlier works to calculate the electronic transition probability parameters utilizing the above mentioned asymptotic expansion technique have also been extended and modified.
