Asymmetric rotator model of odd-mass nuclei
(Elsevier, 1962)
The asymmetric rotator model of Dadydov and Filippov has been extended to odd-mass nuclei by coupling a single nucleon to an inert core of well stabilized asymmetric equilibrium shape. Rotational energies are calculated ...
The application of thin-plate spark chambers to high-energy [pi]-p experiments
(Elsevier, 1963-01)
Characteristic infrared frequencies of rotational isomers of alkyl chlorides
(Elsevier, 1962)
A study of the infrared spectra of primary, secondary and tertiary alkyl chlorides reveals that the frequency of the so-called C-Cl stretching mode is a function of the detailed structure in the vicinity of the C-Cl bond. ...
Influence of defects on the infrared spectra of polymers Presented in part at the Symposium on Spectroscopy of Polymers, American Chemical Society, Chicago, September 1967.
(John Wiley & Sons, Inc., 1969-01)
For an infinitely repeated regular polymer chain structure the only vibrations which are optically active are those in which the phase of the motion is the same in each unit (the factor-group modes). Frequencies for which ...
Low temperature infrared spectra of polyglycines and C—H ... O[bouble bond]C hydrogen bonding in polyglycine II
(Wiley Subscription Services, Inc., A Wiley Company, 1968-03)
Infrared spectra of polyglycines I and II obtained at −170°C. have been compared with those obtained at room temperature. The changes in frequency of some of the C—H stretching bands are consistent with the earlier suggestion ...
Force fields for nitriles
(Elsevier, 1968-11)
A valence force field for nitriles based on the force field obtained for hydrocarbons is found to give very good agreement with the observed bands for several mono- and di-nitrile molecules. The average deviation between ...
Vibrational analysis of chain folding in polyethylene crystals
(John Wiley & Sons, Inc., 1968-05)
The vibration frequencies of a polyethylene crystal lattice have been computed for various structures in which a fully deuterated chain is mixed with a normal chain. Intermolecular potential functions previously developed ...
A force field for secondary chlorides
(Elsevier, 1967-08)
A force field has been derived for monochloro- and 2,4-dichloro-hydrocarbons. The Snyder-Schachtschneider force field for hydrocarbons was used as a starting point, the constants associated with the secondary chlorine being ...
Tetrahedral approximation in normal coordinate calculations of high polymers
(Elsevier, 1965-06)
The crystal structure of poly(bisphenol-A carbonate)
