Raman longitudinal acoustic mode (LAM) studies of folded-chain morphology in poly(ethylene oxide) (PEO). I. Normal mode analysis of LAM of a helical-chain oligomer of PEO
(John Wiley & Sons, Inc., 1990-01-15)
Normal mode analyses were done for the exact structures of model oligomers of PEO to investigate the longitudinal acoustic mode (LAM) in this helical polymer. It quickly became apparent that it is impossible to reproduce ...
An examination of the cyanide derivative of bovine superoxide dismutase with electron-nuclear double resonance
(Elsevier, 1982-05-21)
The Cu(II) sites of native, azido- and cyano-derivatives of bovine superoxide dismutase (superoxide:superoxide oxidoreductase, EC 1.15.1.1) have been examined by electron-nuclear double resonance ENDOR). The ENDOR spectrum ...
Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
Multiple frequency EPR studies on three forms of oxidized cytochrome c oxidase
(Elsevier, 1983-10-17)
Bovine heart mitochondrial cytochrome c oxidase (cytochrome aa3) (EC 1.9.3.1) has been demonstrated to occur in several forms when the redox centers in the protein are thought to be fully oxidized. We report here the results ...
Mixed-crystal infrared studies of chain folding in melt-crystallized polyethylene
(John Wiley & Sons, Inc., 1983-02)
No Abstract.
Transition dipole interaction in polypeptides: Ab initio calculation of transition dipole parameters
(Elsevier, 1984-06-15)
Ab initio calculations of dipole moment derivatives of a model system of N-methylacetamide hydrogen-bonded to two formamide molecules give values for amide I and amide II transition dipole moments consistent with those ...
Mixed-crystal infrared study of chain mobility in untreated and nitric-acid-treated polyethylene single crystals
(John Wiley & Sons, Inc., 1983-11)
No Abstract.
Longitudinal acoustic mode in polymers. II. Solution of the general composite perturbed elastic rod
(John Wiley & Sons, Inc., 1977-10)
The theory of the longitudinal vibrations of a composite rod with perturbing forces at the ends has been generalized by the inclusion of inertial effects at the ends of the rod. The frequencies have been calculated for ...
Vibrational studies of the disulfide group in proteins. Part V. Correlation of SS stretch frequencies with the CCSS dihedral angle in known protein disulfide bridges
(Wiley Subscription Services, Inc., A Wiley Company, 1992-04)
Normal mode calculations have been done on 92 disulfide bridges in 25 known protein structures in order to correlate the SS stretch frequency with the CCSS dihedral angle. It is possible to classify the frequencies into ...
New chain conformations of poly(glutamic acid) and polylysine
(Wiley Subscription Services, Inc., A Wiley Company, 1968-09)
No Abstract.
