Kinetics of Phase Change. I General Theory

The theory of the kinetics of phase change is developed with the experimentally supported assumptions that the new phase is nucleated by germ nuclei which already exist in the old phase, and whose number can be altered by previous treatment. The density...

Forces in molecules

Formulas have been developed to calculate the forces in a molecular system directly, rather than indirectly through the agency of energy. This permits an independent calculation of the slope of the curves of energy vs. position of the nuclei, and may...

The theory of functions

Original conservado en la Biblioteca del Campus de Mostoles de la Universidad Rey Juan Carlos (sign. 517.5 TIT THE).

The Dielectric Polarization of Polar Liquids

An extension of the Onsager theory of dielectric polarization is presented. The local dielectric constant is approximated by the macroscopic dielectric constant of the fluid in a region outside a molecule and its first shell of neighbors rather than in...

Preliminary analysis of functions of the temporal lobes in monkeys.

1we pointed out that the chief symptoms following bilateral temporal lobectomy in the rhesus monkey consist in "psychic blindness" (Seelenblindheit) or visual agnosia, strong "oral" tendencies and profound emotional changes. Our results were primarily...

Polarized light

With the development of practical polarizing sheets, polarized light, long known and employed by science, is being given increasingly wide use in engineering and industry. Its applications in the study of stresses, in photography, stereoscopic motion...

A Method of Obtaining the Expanded Secular Equation for the Vibration Frequencies of a Molecule

A method is described for obtaining the secular equation for the vibration frequencies of a molecule directly in expanded form, i.e. as an algebraic rather than a determinantal equation. The force constants occur literally and the masses may occur either...

Currents Induced by Electron Motion

A method is given for computing the instantaneous current induced in neighboring conductors by a given specified motion of electrons. The method is based on the repeated use of a simple equation giving the current due to a single electron's movement and...

Static solutions of Einstein's field equations for spheres of fluid

A method is developed for treating Einstein's field equations, applied to static spheres of fluid, in such a manner as to provide explicit solutions in terms of known analytic functions. A number of new solutions are thus obtained, and the properties...

Thermodynamics of Crystals and Melting

The Helmholtz free energy,A, of a rigid body is a function of temperature, and of the six homogeneous strain components. If the crystal is to be rigid, three inequalities must be satisfied for the derivatives of A with respect to the six strain components,...

THE GROWTH OF BACTERIOPHAGE

1. An anti-Escherichia coli phage has been isolated and its behavior studied.2. A plaque counting method for this phage is described, and shown to give a number of plaques which is proportional to the phage concentration. The number of plaques is shown...

The Free Energy of Hydration of Gaseous Ions, and the Absolute Potential of the Normal Calomel Electrode

The free energies of hydration of the alkali and halide ions are found to agree reasonably well with the simple expression of Born (—ΔF=(1–1/D)Ne 2/2re ) for solution of charged spheres in a dielectric medium, provided the crystal radii are suitably...

Terrain corrections for gravimeter stations

In this paper the correction for the gravitational attraction of the topography on a gravity station is considered as consisting of two parts; (1) the restricted but conventional “Bouguer correction” which postulates as a convenient approximation...

Studies in Animal Locomotion

1. The integrity of the peripheral sensory nervous system, associated with the skin, muscles, and connective tissue, is not essential for the transmission of a locomotory rhythm along the body of the eel ( Anguilla vulgaris ). The rhythm is determined...

Tumors of the heart and pericardium

Among 1,082 cases of malignant disease appearing in a series of 11,100 consecutive post-mortem examinations performed at the Cleveland City Hospital during the past twenty years, the heart, including the pericardium, was involved by metastatic tumor in...

Fractional-Frequency Generators Utilizing Regenerative Modulation

By the application of the principle of regeneration to certain modulation systems, a generator of submultiple or other fractional frequency ratio may be obtained. A simple example is obtained by considering a second-order modulator whose output is connected...

The Jahn-Teller Effect and Crystalline Stark Splitting for Clusters of the Form XY6

The present article develops the mathematical theory needed in connection with the preceding paper, and with a study of paramagnetic relaxation to appear later. Jahn and Teller have shown that the normal coordinate theory for a molecular cluster such...

Corresponding States for Perfect Liquids

On the basis of certain assumptions concerning the properties of the molecules, and by using classical statistics, the van der Waals theory of corresponding states is derived. No mathematical approximations are involved. Argon, krypton and xenon, which...

Intensities of Electronic Transitions in Molecular Spectra II. Charge-Transfer Spectra

Two related types of high intensity molecular spectra are discussed. These are designated as charge‐resonancespectra and charge‐transferspectra. In the molecular orbital approximation, both these types usually involve transfer of one electron from...

Some Quantum‐Mechanical Considerations in the Theory of Reactions Involving an Activation Energy

The activated complex or transition state method for calculating the absolute rate of a chemical reaction with an activation energy would be rigorously valid if classical mechanics applied to all degrees of freedom. In quantum mechanics, two kinds of...

Analysis of the Near Ultraviolet Electronic Transition of Benzene

The absorptionspectrum of benzene at 2800–2200A has been analyzed. The vibrational structure of the system has been found to be in agreement with the selection rules for a forbidden transition (1 A 1g →1 B 2u ). The transition becomes possible when...

REVERSIBILITY IN EVOLUTION CONSIDERED FROM THE STANDPOINT OF GENETICS1

Intensities of Electronic Transitions in Molecular Spectra I. Introduction

The neglected problem of the theory of the absolute intensities of electronic transitions in molecular spectra is discussed. General equations for dipole strength, Einstein coefficients, mean lifetimes of excited states,f values, and so forth, are collected...

ACUTE MYOCARDIAL INFARCTION NOT DUE TO CORONARY ARTERY OCCLUSION

It is well known that the clinical and electrocardiographic features of coronary thrombosis may be observed in patients in whom a coronary artery thrombus is subsequently not found at necropsy. In such patients the clinical picture may have been caused...

Intensities of Electronic Transitions in Molecular Spectra IV. Cyclic Dienes and Hyperconjugation

The spectra of cyclopentadiene, 1,3‐cyclohexadiene, thiophene, furan, and pyrrole are considered. Theoretical explanations of their departures from the spectra of openchain conjugated dienes are given. The cause of these departures in the cases of cyclopentadiene...
