Energy Expectation Values and the Integral Hellmann–Feynman Theorem: H2+ Molecule
(The American Institute of Physics, 1968-08-01)
It is by now well known that the integral Hellmann–Feynman (IHF) theorem has little quantitative utility for chemically interesting problems, although the formalism potentially affords a ready physical interpretation of ...
Correlation of Rates of Intramolecular Tunneling Processes, with Application to Some Group V Compounds
(The American Institute of Physics, 1960-03)
A method is presented whereby the WKB expression for tunneling frequencies permits correlation of these frequencies for members of homologous series of molecules. The necessary data required are the tunneling rate for one ...
Quantum Calculations of the Velocity Dependence of the Differential and Total Cross Sections for Elastic Scattering of Molecular Beams
(The American Institute of Physics, 1961-02)
The partial wave treatment (phase shift analysis) of the elastic scattering of molecular beams [J. Chem. Phys. 33, 795 (1960)] is applied to the calculation of the velocity dependence of the differential and total cross ...
Effect of Wire Cross Section on the First Pulse of an Exploding Wire
(The American Institute of Physics, 1965-09)
The optimum discharge in an exploding wire circuit is described. In this type of discharge, the stored energy of the capacitor discharges completely during the first pulse of the exploding wire phenomenon. It was determined ...
General Exact Solutions for the Diffusion Equations of Momentum, Heat, and Mass in Spiral Viscous Flows
(The American Institute of Physics, 1964-06)
The diffusion equations of momentum, heat, and mass are solved for spiral flows of incompressible viscous fluids. General exact solutions for the steady‐state distributions of velocity, temperature, and concentration are ...
ESR of Alkali Metal Dinitrobenzene Salts in Dimethoxyethane DME
(The American Institute of Physics, 1967-01-01)
Use of a Linear Staircase Generator in Displaying Synchronized Pulse Activity
(The American Institute of Physics, 1968-09)
Flow Field of a Bunsen Flame according to Source Sheet Approximation
(The American Institute of Physics, 1965-09)
A volume source sheet plus a uniform flow is used to represent the flow field of a two‐dimensional Bunsen flame when the density ratio of the unburned to burned gases is 5.5. The unknown flame shape is determined by the ...
