The Hydrogen Isotope Exchange Reaction
(The American Institute of Physics, 1940-03)
The possibility of deriving the equilibrium constants for the higher deuterium substitutions from the isotope exchange coefficient is examined with the aid of calculations on the ammonia and methane reactions with water. ...
Ion‐Migration Phenomena Observed with the Electron Microscope
(The American Institute of Physics, 1945-06)
Hindered Rotation in Ethyl Alcohol
(The American Institute of Physics, 1949-02)
Previous evaluations of the barriers hindering the internal rotations in ethyl alcohol are shown to be unsatisfactory because they fail to produce agreement between molecular and calorimetric entropies over a wide enough ...
Thermodynamic Properties of the Internal Rotator. Double Minimum with Attractive Forces
(The American Institute of Physics, 1948-06)
A previously outlined general method of calculating thermodynamic properties for an unsymmetrical internal rotation is applied to a double minimum with attractive forces, for which the potential energy has two maxima at ...
Studies on the Structure of Thin Metallic Films by Means of the Electron Microscope
(The American Institute of Physics, 1943-06)
A study was made of thin films of aluminum, cadmium, copper, gold, magnesium, and zinc using an RCA electron microscope capable of 30A resolving power. The films were formed by evaporation and condensation on collodion ...
Comparative Thermodynamic Properties of the Restricted Rotator and the Harmonic Oscillator
(The American Institute of Physics, 1947-06)
The differences between the thermodynamic properties of the restricted internal rotator and a defined harmonic oscillator are expressed within narrow limits as a function of the single variable V/RT, where V is the height ...
Focusing in a Semicircular Magnetic Spectrometer
(The American Institute of Physics, 1949-12)
