Electronic Structure and Stability of Hydrogen Halides and of Complex Ions XO

(1) It is shown that in the hydrogen halide molecules (internuclear distance ro) the proton penetrates the electronic shell of the anion to a depth which for the simplified case of spherical symmetry can be characterized by the condition: The amount of negative charge beyond the sphere of radius ro equals Ie, (2) From the dipole moments p.=xero of the hydrogen halide molecules it can be concluded: The wave mechanical distribution of the negative charge of the free halide ions is changed by the introduction of the protein in such a way that the center of gravity of an amount of charge equal to (1-x)e is shifted from the halogen nucleus to the proton. The fraction (1x) increases with the electronic polarizability of the anion, and would be equal to 1 for an ion of infinitely large polarizability, leading to a completely unpolar type of bind-
