A new determination of the ground state interatomic potential for He2
A simple accurate potential of the HFD-B form, which appears to be the best characterization of the He-He interaction constructed to date, is presented. It has been fitted to low temperature secondExpand
Irreducible Cartesian Tensors
This paper considers certain simple and practically useful properties of Cartesian tensors in three‐dimensional space which are irreducible under the three‐dimensional rotation group. Ordinary tensorExpand
Rovibrational structure and potential energy function of the X 0⁺ ground electronic state of ArXe
Abstract Rotationally resolved (1 + 1′) resonance-enhanced two-photon ionization spectra of the D 0 + ,C 1 ← X 0 + band systems of several isotopomers of ArXe were recorded at high resolution in theExpand
Magnetoviscosity of Colloidal Suspensions
A theoretical description of the effect of an applied magnetic field on the viscosity of a colloidal suspension of single-domain ferromagnetic particles is given from the point of view of linearizedExpand
Dicke narrowing and collisional broadening of spectral lines in dilute molecular gases
A unified description of pressure broadening and Dicke or diffusional narrowing of spectral lines is presented from the point of view of a quantum mechanical kinetic theory. The present descriptionExpand
Kinetic theory-memory equation approach to nuclear magnetic relaxation in molecular gases. Hydrogen binary mixtures
Abstract Expressions are obtained for T 1 in binary mixtures of H 2 with the noble gases and with nitrogen using a kinetic theory-memory equation approach to NMR. A re-analysis of recent experimentalExpand
Inelastic differential and integral cross sections for 2S+1.SIGMA. linear molecule-1S atom scattering: the use of Hund's case b representation
Exact close-coupled scattering equations are established for multiplet-..sigma.. molecule-structureless atom collisions by using a Hund's case (b) coupling scheme for the description of theExpand
Accuracy of recent potential energy surfaces for the He-N2 interaction. I. Virial and bulk transport coefficients.
A new exchange-Coulomb semiempirical model potential energy surface for the He-N2 interaction has been developed. Together with two recent high-level ab initio potential energy surfaces, it has beenExpand
Microwave spectra of the Ne–N2 Van der Waals complex: Experiment and theory
High-resolution microwave spectra of the ground state 20Ne–14N2, 20Ne–15N2, 22Ne–14N2, and 22Ne–15N2 Van der Waals complexes, involving rotational levels up to J=4, are reported. Interpretation andExpand
An exchange–Coulomb model potential energy surface has been developed for the N2–Ar interaction. This potential energy surface is based upon recent results for the Heitler–London interaction energy,Expand
