Cusp Conditions for Molecular Wavefunctions
The conditions on the behavior of a wavefunction for a system of charged particles near the coalescence of any two of them are derived. The new features of the derivation are: (a) the fixed‐nucleusExpand

Recent Developments in Perturbation Theory
Publisher Summary The purpose of this chapter is to provide information on the recent developments in perturbation theory. In recent years, there is a great increase of interest in the application ofExpand

Branch point singularities in the energy of the delta-function model of one-electron diatoms
Two different perturbation series (the polarization expansion and a united-atom expansion) of the ground state energy of the delta-function model for one-electron diatoms are studied and the radii ofExpand

The relationship between the Rayleigh‐Schrödinger and asymptotic perturbation theories of intermolecular forces
The relation of the straightforward Rayleigh--Schroedinger perturbation theory for the interaction of two atoms to the asymptotic exchange theory is described. The one-electron case of a hydrogenExpand

Extraction of the lanthanides with acetylacetone
Abstract Acetylacetone extracts the lanthanides from aqueous solution at pH values between four and six. The solubility and extractability of the rare earth acetylacetonates vary with the ionic radiiExpand

Icosahedral water clusters
Abstract Clusters containing 57 and 60 water molecules have been studied theoretically in the search for stable species which might explain the observed millimetre-wave absorption spectra of waterExpand

Perturbation theory of the Hooke's law model for the two-electron atom
The Hooke model for the two‐electron atom replaces the electron–nuclear interaction by a harmonic oscillator potential, but retains the Coulomb repulsion of the electrons. The first‐orderExpand

The Rayleigh–Schrodlinger perturbation energies E(n) for the ground state of the Hooke's law model atom are calculated through tenth order. The E(n) are expressed as singly infinite sums whose termsExpand
