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 ...

(University of Michigan Museum of Zoology, 1948)
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 ...
