The theory of isoelectronic molecules has been applied to three sequences of ground-state diatomic molecules. The global behaviors of their dissociation energies, force constants, and bond distances are examined and the sequences compared with one an

We are creating a World-Wide Web (WWW) introductory chemistry site that will incorporate many key features of an electronic chemistry curriculum, including flexibility, interactivity, extensibility, diversity, and self-assessment. The site will be ac

Difference equations for moment integrals which contain powers of the Airy functionAi(z) and its derivativeAi'(z) i.e. $$\int_0^\infty {z^n [Ai(z)]^\alpha dz,} \int_0^\infty {z^n [Ai'(z)]^\alpha dz,} $$ are obtained. These equations are easily solved

A formalism that describes the variation of the spectroscopic properties, De, Re, and ke, of homonuclear, diatomic molecules, with the number of molecular electrons has been developed. The theory describes the interrelation of these properties and pr

We integrate the steady state diffusion equation in a membrane whose permeability is weakly inhomogeneous in the direction of diffusion x (i.e. a laminated membrane) and depends linearly on the activity. We show that this solution can be closely appr

A perturbative procedure due to Bender et al. (here referred to as the BMPS procedure) [J. Math. Phys. 30, 1447 (1989)] and useful in solving difficult nonlinear problems, has been used here to solve the Thomas–Fermi (T–F) equation. The present w

Using the exact generalized Green's functions for the first three energy levels of the hydrogen atom, we have computed the static dipole polarizabilities for the S states. The calculations were done analytically and exactly on a digital computer usin

A theory of isoelectronic molecules which describes stable and metastable members of a sequence has been developed. To achieve this synthesis, it has been necessary to require that the total electronic energy surface E(R,Z,Z') for the sequence contai

A general theory of isoelectronic diatomic molecules is developed and numerical calculations are performed for the fourteen electron sequence. Calculated values of equilibrium bond distances, force constants, and dissociation energies compare well wi

Electronic energy curves for diatomic molecules come in a wide variety of shapes. More categorically, these correspond to stable, metastable or repulsive states. We propose that a great deal of this apparently diverse behavior might in fact be contai
