The vibration-rotation energies of tetrahedral XY4 molecules : Part I. Theory of spherical top molecules
(Elsevier, 1961)
The theory of vibration-rotational perturbations in tetrahedral XY4 molecules has been reexamined in the light of the modern theory of angular momentum coupling. It is shown that, even to third order of approximation, the ...
Lattice‐Frequency Studies of Crystalline and Fold Structure in Polyethylene
(The American Institute of Physics, 1968-10)
The assignment of the 71 cm−1 band in the infrared spectrum of polyethylene to the B1u translational lattice vibration has been confirmed by dichroism studies on an a‐axis oriented sample. This permits confident use of the ...
Vapor‐Phase Charge—Transfer Complexes. Diethyl Sulfide—Iodine
(The American Institute of Physics, 1965-11-01)
Erratum: Discontinuous Change of Binding Type in the Series of Monohydrides. II. Place of Discontinuity
(The American Institute of Physics, 1965-05-15)
Slanting of a Magnetically Stabilized Electric Arc in Transverse Supersonic Flow
(The American Institute of Physics, 1966-04)
Experimental observations are presented which indicate the existence of a convective interaction mechanism affecting the direction and stability of electric current in a flowing gas. The observations were made of an electric ...
Origins of Characteristic Bands in the Infrared Spectra of Isotactic Polystyrene and Isotactic Poly (Ring‐d5 Styrene)
(The American Institute of Physics, 1961-11)
The origins of characteristic bands in the infrared spectrum of isotactic polystyrene have been studied with the aid of the spectrum of isotactic poly (ring‐d5 styrene). It is found that these bands can be classified into ...
Effect of Chemisorbed Oxygen on Photovoltaic and Photoconductive Processes in Rutile
(The American Institute of Physics, 1964-06)
Adsorbed oxygen increases both the response and the response time for the photovoltaic effect in rutile.The model for the effect of chemisorbed oxygen on the photoconductivity has been modified to take into consideration ...
Extrema in Velocity Dependence of Total Elastic Cross Sections for Atomic Beam Scattering: Relation to Di‐atom Bound States
(The American Institute of Physics, 1962-10-15)
Boundary‐Layer Transition on a Cooled Rough Sphere in Hypersonic Flow
(The American Institute of Physics, 1964-08)
Measurements are given of the combined effects of two‐dimensional roughness and surface cooling on boundary layer transition at 45° from the stagnation point on a sphere in simulated hypersonic flow. With the roughness ...
