The concept of intramolecular binding is given a precise definition in a way that relates binding to the forces acting on the nuclei in a diatomic molecule. A consequence of the definition is that the space around the nuclei may be separated into binding and antibinding regions. These regions are described and they depend on the Coulomb law of force and on the ratio of the nuclear charges: the internuclear distance is simply a scale parameter. The influence of a single electron on the binding due to other electrons is briefly discussed.* Communication VII on "The Electronic Structure of Molecules.
Derivation of the electric dipole-dipole interaction as an electric hyperfine interaction Am.A mathematical model, the spherical model, of electric dipole-dipole interaction in simple lattices is discussed. The partition function for the system, assuming just nearest neighbor interaction, is evaluated for one-and three-dimensional simple lattices. Only the three-dimensional lattice exhibits a phase transition. The transition is discussed. The transition behavior in the presence of an external field is also analyzed, and the electric susceptibility is computed.
A theory of electrolytes founded on the principles of statistical mechanics is presented. The primary physical assumptions are: (1) point ions, and (2) small fluctuations. The theory is a modification of Kramers' theory of electrolytes. The modification consists of a more physically accurate development of assumption (2). The main result of the present theory is that a partition function for the electrolyte is obtained for all concentrations, whereas Kramers' theory breaks down beyond a limiting concentration. The deviation from the Debye-Hueckel limiting law is in the direction of the experimental observations.
LETTERS TO THE EDITORQ-value of -(1.006:4=0.010) Mev has been given 3 corresponding to a mass difference of (0.22±0.01) Mev.The new method of determining the energy-release in electron capture processes may be applied even in some cases where the disintegration goes over an excited level of the daughter nucleus with the emission of a nuclear 7-ray. A more detailed account will be published in Helvetica Physica Ada. We thank Professor P. Scherrer for his interest in this work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
