The Infra‐Red Absorption Spectrum of Boron Trifluoride
(The American Institute of Physics, 1939-07)
The infra‐red absorption spectrum of BF3 has been studied under high resolution from 400 cm—1 to 3000 cm—1. The active fundamentals v2, v3 and v4 and the overtone 2v3 have been observed. The parallel fundamental v2 has ...
Cloud Chamber for Nuclear Disintegration Studies
(The American Institute of Physics, 1937-11)
Construction of an entirely automatic cloud chamber particularly adapted to the study of the high energy electrons produced in artificial disintegration experiments is described. Air core coils which are capable of producing ...
The Potential Functions of the Methyl Halides
(The American Institute of Physics, 1939-07)
The problem of the potential functions of the methyl halides is re‐examined in an attempt to find a function which is both adequate and simple. A valence form of potential was tried which contained four constants: k1, the ...
The Infra‐Red Absorption Spectrum of Methyl Alcohol
(The American Institute of Physics, 1938-09)
Using a grating spectrometer having a KBr foreprism the spectrum of methyl alcohol vapor was studied in the region from 2.5 to 26μ. This molecule has bands at 3683, 2978, 2845, 2054, 1477, 1455, 1340, 1034.18 cm—1 and a ...
A Complete Geiger‐Müller Counting System
(The American Institute of Physics, 1939-01)
Constructional details are given of a complete Geiger‐Müller counting system consisting of a stabilized high voltage supply, Neher‐Harper coupling circuit and vacuum‐tube scale‐of‐eight feeding a Cenco counter stage. The ...
The Mobility Method of Computing the Vibration of Linear Mechanical and Acoustical Systems: Mechanical‐Electrical Analogies
(The American Institute of Physics, 1938-06)
The Infrared Association Band of a Heavy Alcohol
(The American Institute of Physics, 1937-12)
The Raman Spectra of Deutero‐acetones and Methyl Alcohol‐d
(The American Institute of Physics, 1936-08)
The Raman Spectra of the Methyl Alcohols, CH3OH, CH3OD, and CH2DOD
(The American Institute of Physics, 1937-12)
Measurements of the Raman spectra of CH3OH, CH3OD, and CH2DOD, produced by the mercury lines at 2536 and 4358A units, are analyzed to yield a provisional assignment of the fundamental frequencies. The significance of the ...
The Absorption Spectra of Cyclopropane, Ethylene Oxide, Ethylene Sulfide, and Ethylene Imine in the Photographic Infra‐Red
(The American Institute of Physics, 1938-10)
The absorption spectra of cyclopropane, ethylene oxide, ethylene sulfide, and ethylene imine have been investigated in the region between 7000 and 12,000A and the stronger bands have been assigned as third harmonics of the ...
