Infrared Dichroism of Mutually Perpendicular Normal Modes in Oriented High Polymers
(The American Institute of Physics, 1957-12)
Hindered Rotation in Molecules with Relatively High Potential Barriers
(The American Institute of Physics, 1957-01)
The theory of hindered rotation has been applied to the type of asymmetric molecule in which the hindering barrier is high enough so that the hindered rotation splittings of the energy levels are small compared with the ...
Equipartition of Energy and Local Isotropy in Turbulent Flows
(The American Institute of Physics, 1957-10)
Homogeneous turbulence in which 〈v2〉 = 〈w2〉 ≠ 〈u2〉 was produced experimentally, where 〈u2〉, 〈v2〉, and 〈w2〉 are the mean‐square turbulent velocities in x, y, and z direction, respectively. The decay of turbulence and the ...
Exact Current‐Voltage Relation for the Metal‐Insulator‐Metal Junction with a Simple Model for Trapping of Charge Carriers
(The American Institute of Physics, 1957-04)
The exact solution to the diffusion equation for one kind of charge carrier is obtained for the metal‐insulator‐metal junction where trapping of the charge carriers may occur in the body of the insulator. The effect of ...
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 ...
Vibration‐Hindered Rotation Interactions in Methyl Alcohol. The J=0→1 Transition
(The American Institute of Physics, 1957-01)
The hindered rotation fine structure of the J=0→1, K=0→0 transition which has been observed by Venkateswarlu, Edwards, and Gordy in normal methanol as well as in five additional isotopic species can be understood only ...
Selection rules for the vibrational spectra of high polymers
(Elsevier, 1957)
With the aid of the Born cyclic postulate, the selection rules for the vibrational modes of a crystalline polymer and an oriented infinite chain-molecule have been discussed. The necessary conditions for the modes to be ...
Reversible properties of polycrystalline ferromagnets--I , : Theory of the expected variation of the reversible properties with magnetization
(Elsevier, 1957)
Using a statistical model, equations are developed for the variation of the reversible susceptibility both parallel with and normal to the biasing magnetization as a function of the magnetization assuming that the ...
Reflection of Sound from a Surface of Saw‐Tooth Profile
(The American Institute of Physics, 1957-11)
A variational method is used to calculate the energy diffracted into the various orders produced when a plane acoustic wave is incident on a periodic, pressure‐release surface of saw‐tooth shape. The results of companion ...
