Transmission and Reflection of Plastics and Metal Blacks in the Far Infra‐Red
(The American Institute of Physics, 1940-11)
Transmissions and reflections have been measured at nine wave‐lengths between 20.7μ and 152μ for a number of plastics and special surfaces. The residual rays from crystals were used as sources of approximately monochromatic ...
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. ...
A Method of Photographing a Cloud Chamber between the Poles of an Iron Magnet
(The American Institute of Physics, 1947-10)
The Vibration Spectra of Hydrazoic Acid, Methyl Azide, and Methyl Isocyanate The Thermodynamic Functions of Hydrazoic Acid
(The American Institute of Physics, 1940-05)
The vibration spectra of hydrazoic acid, methyl azide, and methyl isocyanate have been investigated in the spectral region between 2 and 20μ. Correlation of the spectra of these structurally similar molecules has made ...
Electromechanical Lead Networks for A.C. Servo Mechanisms
(The American Institute of Physics, 1949-11)
The characteristics of conventional a.c. lead networks for a.c. servo mechanisms are compared to the characteristics of d.c. lead networks. Electromechanical lead networks for a.c. servo mechanisms having superior ...
Automatic Stabilization of the Overvoltage on a Geiger Counter
(The American Institute of Physics, 1949-12)
Contribution of the Deviation from Perfect Gas Behavior to the Entropy and Heat Capacity. Water and Benzene
(The American Institute of Physics, 1949-04)
The properties of water vapor are used to illustrate the point, previously found true for ethyl alcohol, that the modified Berthelot equation of state may not give a satisfactory evaluation of the deviation of thermodynamic ...
