Binding Regions in Diatomic Molecules
(The American Institute of Physics, 1951-02)
The concept of intramolecular binding is given a precise definition in a way that relates binding to the forces acting on the nuclei in a diatomic molecule. A consequence of the definition is that the space around the ...
The Structure of Polymer‐Plasticizer Gels As Shown by the Electron Microscope
(The American Institute of Physics, 1950-02)
Improving Differential Amplifier Rejection Ratios
(The American Institute of Physics, 1950-08)
The Infra‐Red Absorption Spectrum of Diborane
(The American Institute of Physics, 1950-05)
The infra‐red absorption spectrum of diborane has been examined under high resolution from 3.7μ to 30μ with automatic recording grating spectrometers. The rotational fine structure in two bands of each of the three types ...
A Statistical Approach to the Space‐Charge Distribution in a Cut‐Off Magnetron
(The American Institute of Physics, 1952-09)
When the anode potential of a nonoscillating magnetron is lower than the cut‐off potential, the discrete electron‐to‐electron interaction has an effect on the space‐charge distribution which would be negligible if only ...
Partition Function for Internal Rotation in Methanol and Similar Molecular Models
(The American Institute of Physics, 1957-04)
Methanol falls outside the range of variables within which the internal rotator partition function and its required derivatives have been dependably calculated by the relatively simple methods of Pitzer and Gwinn. For such ...
Pressure Response in Supersonic Wind‐Tunnel Pressure Instrumentation
(The American Institute of Physics, 1953-11)
In the development of high‐speed aircraft, rockets, missles, etc., wind‐tunnel pressure measurements at supersonic velocities are necessary to determine certain aerodynamic characteristics. Because of the lack of knowledge ...
High energy, high current synchrotron injector
(IOP Publishing Ltd, 1959-07-01)
The construction and testing of a pulsed 450 keV injector for an electron synchrotron are described. High voltage is obtained with a spark gap and pulse transformer. The electron-optical system consists of a series of ...
Stretching Force Constant of the Carbonyl Bond in Unconjugated Ketones
(The American Institute of Physics, 1956-04)
The secular equation derived for the normal frequencies of a Y‐shaped C2CO model can be used with fair accuracy to obtain the carbonyl bond force constant from the measured carbonyl frequency of any symmetrical ketone if ...
