Lipoxygenase isoenzymes: A spectroscopic and structural characterization of soybean seed enzymes
(Elsevier, 1989-02-15)
Applying recent developments in protein purification techniques, a number of lipoxygenase isoenzymes have been isolated in satisfactory quantities for a detailed physical and structural characterization. Four seed isoenzymes ...
Vibrational analyses of 2,4-dichloropentane and 2,4,6-trichloroheptane
(Elsevier, 1974-04)
This study of the vibrational spectra of 2,4-dichloropentane and 2,4,6-trichloroheptane uses normal coordinate calculations as a probe for the presence of different molecular conformers. The calculations use a complete ...
Vibration-rotation energies of tetrahedral XY4 molecules : Part II. The fundamental [nu]3 of CH4
(Elsevier, 1961)
The matrix elements derived in the first paper of this series are used to compute the frequencies of the tetrahedral fine structure components of the rotational lines of the fundamental [nu]3 of CH4. The theoretically ...
Self Assembly and Optical Properties of Dendrimer Nanocomposite Multilayers
(WILEY-VCH Verlag, 2007-08-07)
Ultrathin multilayers are important for electrical and optical devices, as well as for immunoassays, artificial organs, and for controlling surface properties. The construction of ultrathin multilayer films by electrostatic ...
Charge-density domains in photoexcited quantum-well structures
(Elsevier, 1990-04-01)
We present theoretical and experimental results on the dielectric response of an electron-hole plasma confined to a quantum-well. Hartree calculations reveal large nonlinearities in the screening properties which, when ...
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 ...
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 ...
Comment on enhanced Raman scattering from adsorbates on semiconductor surfaces
(Elsevier, 1984-11-02)
A recently published model of surface enhanced Raman scattering from adsorbed molecules on semiconductor surfaces is compared to our experimental results for amorphous carbon on PbTe. The model fails to account for the ...
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 ...
