Electronic Population Analysis on LCAO–MO Molecular Wave Functions. I

With increasing availability of good all‐electron LCAO MO (LCAO molecular orbital) wave functions for molecules, a systematic procedure for obtaining maximum insight from such data has become desirable. An analysis in quantitative form is given here...

Economic growth and income inequality

The process of industrialization engenders increasing income inequality as the labor force shifts from low-income agriculture to the high income sectors. On more advanced levels of development inequality starts decreasing and industrialized countries...

Ferromagnetic materials

In this chapter, we will restrict our attention to the ferrites and a few other closely related materials. The great interest in ferrites stems from their unique combination of a spontaneous magnetization and a high electrical resistivity. The observed...

Theory of Elasticity and Consolidation for a Porous Anisotropic Solid

The author's previous theory of elasticity and consolidation for isotropic materials [J. Appl. Phys. 12, 155–164 (1941)] is extended to the general case of anisotropy. The method of derivation is also different and more direct. The particular cases...

Electronic Population Analysis on LCAO[Single Bond]MO Molecular Wave Functions. II. Overlap Populations, Bond Orders, and Covalent Bond Energies

LCAO molecular orbital overlap populations give in general much more flexible and widely useful measures of the non‐Coulombic parts of covalent bond energies than do LCAO bond orders. They are immediately applicable to both π and σ bonds, including...

Solar energy

Solar energy can now compete with animal power and manpower, but there will be no era of solar prosperity in the near future. With the coming shortages in fuel supply, however, extensive programs of research and development on the utilization of solar...

Slow electrons in a polar crystal

A variational principle is developed for the lowest energy of a system described by a path integral. It is applied to the problem of the interaction of an electron with a polarizable lattice, as idealized by Frohlich. The motion of the electron, after...

Available Potential Energy and the Maintenance of the General Circulation

The available potential energy of the atmosphere may be defined as the difference between the total potential energy and the minimum total potential energy which could result from any adiabatic redistribution of mass. It vanishes if the density stratification...

The Influence of Solid Boundaries upon Aerodynamic Sound

An extension is made to Lighthill's general theory of aerodynamic sound, so as to incorporate the influence of solid boundaries upon the sound field. This influence is twofold, namely (i) reflexion and diffraction of the sound waves at the solid boundaries,...
