Infrared studies of conformational changes in polyvinyl chloride
(John Wiley & Sons, Inc., 1964-02)
Analysis of the infrared spectrum of polyvinyl chloride has permitted the identification, from the frequencies of the several C[bond]Cl stretching bands, of the chain conformations which are associated with particular ...
New chain conformations of poly(glutamic acid) and polylysine
(Wiley Subscription Services, Inc., A Wiley Company, 1968-09)
No Abstract.
Infrared spectra and assignments for polyvinyl chloride and deuterated analogs
(John Wiley & Sons, Inc., 1963-08)
Deuterated analogs of polyvinyl chloride (PVC) have been prepared and their infrared spectra analyzed as an aid to the more detailed assignment of bands in the spectrum of PVC. The following deuterated polymers were studied: ...
Circular dichroism of the “random” polypeptide chain
(Wiley Subscription Services, Inc., A Wiley Company, 1969-09)
The circular dichroism (CD) spectrum of an unordered polypeptide chain does not correspond, as has been assumed heretofore, to that of a charged chain such as poly- L -glutamic acid or poly- L -lysine. The latter have been ...
Influence of counterions on the helical conformations of charged polypeptide chains
(Wiley Subscription Services, Inc., A Wiley Company, 1969-11)
No Abstract.
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. ...
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 ...
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 ...
