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 ...
Mounting of Stained Stripping Film Autoradiographs
(The American Institute of Physics, 1956-11)
Bistatic Radar Cross Sections of Surfaces of Revolution
(The American Institute of Physics, 1955-03)
The results obtained by applying the current‐distribution method to the problem of approximating the scattering cross section, when the transmitter and receiver are separated, are presented for several simple geometric ...
Plasma oscillations
(Elsevier, 1959-07)
The equivalence of the Landau and Van Kampen treatments of the initial value problem for plasma oscillations is demonstrated. Using completeness and orthogonality theorems for the normal modes, and integral representation ...
Recurrence Relations for Prolate Spheroidal Wave Functions
(Stanford Research InstituteWiley Periodicals, Inc., 1953-04)
Interaction of Methylene Deformation Frequencies in Paraffin Crystals
(The American Institute of Physics, 1953-02)
Rotation spectrum of methyl alcohol
(Elsevier, 1959)
The rotation spectrum of methanol vapor has been measured from 50 to 457 cm-1. Combining these data with the work of Borden and Barker provides an accurate map of the spectrum to 625 cm-1 together with some provisional ...
Thermodynamic Properties of the Internal Rotation in Methyl Alcohol Vapor from 200 to 500°K
(The American Institute of Physics, 1950-08)
At ordinary and lower temperatures the thermodynamic properties of the methyl alcohol internal rotation are beyond the limits of available tabulations. For any internal rotator, of a given symmetry, with a fixed moment of ...
Kinetics of the Thermal Decomposition of Dimethylmercury. I. Cyclopentane Inhibition
(The American Institute of Physics, 1959-03)
The kinetics of the pyrolysis of gaseous dimethylmercury have been studied in the presence and absence of cyclopentane inhibitor from 290–375°C for the inhibited and 265–350°C for the uninhibited reactions. The decomposition ...
