The Low Frequency Fundamental Band of Ethane at 12μ
(The American Institute of Physics, 1942-02)
The Design of a Magnetic Beta‐Ray Spectrometer
(The American Institute of Physics, 1940-01)
A magnetic beta‐ray spectrometer of high resolution has been constructed. The theory of the resolution of this instrument has been investigated in detail and applied to the design of the slit system. The effects of scattering ...
The Head‐On Collision of a Shock Wave and a Rarefaction Wave in One Dimension
(The American Institute of Physics, 1948-04)
A procedure for investigating the strengthening of a shock which collides head‐on with a rarefaction wave is suggested and is carried through for the case in which the entropy jump across the shock is small enough to be ...
Direct Centrifugation onto Electron Microscope Specimen Films
(The American Institute of Physics, 1944-10)
Isotopic Exchange Between Carbon Tetra‐bromide and Bromine
(The American Institute of Physics, 1941-09)
The Rotational Structure of the Hydrazoic Acid Bands in the Photographic Infra‐Red
(The American Institute of Physics, 1940-02)
The third and fourth harmonics of the N☒H stretching frequency in hydrazoic acid, at 9547.31 and 12,412.19 cm—1, respectively, have been studied photographically under high dispersion. The rotational structure has been ...
The Infra‐Red Spectrum of C2H6
(The American Institute of Physics, 1949-02)
The infra‐red spectrum of C2H6 gas has been studied in the region between 1.6 and 13μ with a spectrometer of high resolving power. From measurements on four resolved ∥ bands the value IB0 = (42.234±0.011)×10−40 g cm2 has ...
A Shadow Casting Unit for the RCA Electron Microscope
(The American Institute of Physics, 1945-10)
Small Spherical Particles of Exceptionally Uniform Size
(The American Institute of Physics, 1949-02)
