    Notes: [Auszug] IN a very important paper (Phil. Mag., vol. 33, p. 521 ; 1917), Silberstein developed a theory of molecular refractivity based on the idea that the electric doublets induced by the field of the light wave in the atoms composing the molecule influence each other, the result of such atomic ...

    Notes: [Auszug] IN recent papers1 we have shown how a correlation of the principal diamagnetic susceptibilities of an organic crystal with those for the molecules of the substance, offers a convenient method for determining the orientations of the molecules in the crystal lattice. The crystal of ...

    Notes: [Auszug] PROF. W. L. BRAGG1 explains the strong birefringence of some carbonates and nitrates as being due to the interaction of the optical dipoles induced in the component atoms. For example, X-ray analysis shows that the carbonate ions in calcite have a plane structure, their planes ...

    Das magnetische Verhalten von Ammoniummanganosulfat-Hexahydrat bei niedrigen Temperaturen (1931)

    Notes: Zusammenfassung Die kürzlich von Jackson und de Haas ausgesprochene Vermutung, daß die magnetischen Momente des Mn++-Ions im Ammoniummanganosulfatkristall sich mit der Richtung ändern, beruht auf Rechenfehlern. In Wirklichkeit verhält sich der genannte Kristall in wesentlich derselben Weise wie andere paramagnetische Kristalle.
