Rittner. J. Chem. Phys. 19, 1030 (1951). en_US dc.description Author Institution: Department of Physics, Georgetown University en_US dc.description.abstract “Dunham expansions have been carried out for the Heitler-London potential for $H_{2}$ (as a simple model for covalent molecules), And for the leading terms of Rittner’s $potential^{1}$ (as a simple model for ionic molecules). The latter has been applied to alkali and earth halides. Of particular interest are the resulting values of $Y_{30} (\omega_{e} y_{0})$, and the ratio of the dissociation energy for the potential to the linearly extrapolated value. For the Heitler-London potential $Y_{30}$ is negative and $D_{o}/D_{lin} =0.80$. This indicates negative curvature for a $\Delta G$ vs. v curve near equilibrium and rapid convergence of vibrational levels near dissociation. $Y_{an}$ is positive from Rittner’s potential and$D_{o}/D_{lin} \sim 2.5$. Values of the other spectroscopic constants will be presented. The ranges of convergence of the Heitler-London and Rittner expansions both appear to be $o < r < 2r_{e}$. Heitler-London coefficients of higher powers of $(r-r_{e})/r_{e}$. are close to values obtained from pure Coulomb repulsion. Problems connected with numerical application of Dunham’s technique will be discussed.” en_US dc.format.extent 112112 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title POWER SERIES EXPANSIONS ABOUT EQUILIBRIUM OF THE HEITLER LONDON AND RITTNER VIBRATIONAL $POTENTIALS^{*}$ en_US dc.type article en_US
