Determination of Object Thickness in Electron Microscopy
(The American Institute of Physics, 1941-10)
It is proposed that the thicknesses of electron microscope objects be determined by measuring the diminution in intensity of the electron beam caused by the object. Since this method would only be applied to specimens so ...
One‐Sided Polarization of Ions in Vapor Molecules
(The American Institute of Physics, 1941-04)
The Entropy of Acetic Acid
(The American Institute of Physics, 1941-12)
From third law measurements, vapor pressures and vapor densities, the entropy of the acetic acid monomer at 25° and one atmosphere is 69.4±1.0 e.u. The value 68.7 is calculated from the vapor phase ethyl acetate equilibrium. ...
Incomplete Dissociation in Solutions of Strong Electrolytes
(The American Institute of Physics, 1941-03)
The Infra‐Red Absorption Spectrum of Propane
(The American Institute of Physics, 1941-07)
Of the twenty‐seven internal degrees of freedom of propane, all nondegenerate, twenty‐two may appear as fundamental absorption bands. These bands fall into three symmetry classes, designated A1, B1 and B2, and distinguishable ...
Isotopic Exchange Between Carbon Tetra‐bromide and Bromine
