Normal coordinate analyses of molecules with the amide group
(Elsevier, 1971-01)
Normal coordinate analyses have been performed on molecules with the amide group using force constants transferred from N-methylacetamides and polyamides. The molecules involved were hexamethylenedipropionamide, ...
Structure of normal and contracted tail sheaths of T4 bacteriophage
(Elsevier, 1967-07-28)
The structural arrangement of protein subunits in extended and contracted tail sheaths of T4 bacteriophage has been studied by optical diffractometry of electron micrographs. The analysis of such diffraction patterns shows ...
Comprehensive force field for multiply-chlorinated hydrocarbons
(Elsevier, 1990)
A force field is presented that has been optimized for chlorinated hyrocarbons containing isolated, vicinal, and geminal secondary chlorines. For carbon--chlorine stretch modes, 74 frequencies in 10 molecules are reproduced ...
Electromagnetic effects in the Surface Enhanced Raman Scattering from a molecule at a liquid Hg surface
(Elsevier, 1981-09-02)
In a previous publication the image enhancement effect and the enhanced radiation due to near field excitation of surface roughness were calculated for a finite-size molecule above a metal described by a nonlocal dielectric ...
Lack of correspondence between the room-temperature phosphorescence decay-components and Trp residues in a series of Trp-->Cys or Trp-->Phemutants of human carbonic anhydrase II
(Elsevier, 1994-10-17)
The room temperature phosphorescence of native human carbonic anhydrase (CA), and several mutants of this enzyme has been investigated. In these mutants the seven tryptophan residues in the native protein have sequentially ...
Comments on "the interpretation of the EPR and Mossbauer spectra of two-iron, one-electron iron-sulfur proteins"
(Elsevier, 1971-12-03)
Evidence is presented indicating that the note mentioned in the title is incorrect in two important aspects. 1.) According to our results of ENDOR spectroscopy and computer simulations of Mossbauer spectra, the conclusions ...
Structure and function in the isolated reaction center complex of Photosystem II: energy and charge transfer dynamics and mechanism
(Kluwer Academic Publishers; Springer Science+Business Media, 2002-05)
The dynamics of energy and charge transfer in the Photosystem II reaction center complex is an area of great interest today. These processes occur on a time scale ranging from femtoseconds to tens of picoseconds or longer. ...
Infrared spectra of high polymers : Part IX. Polyethylene terephthalate
(Elsevier, 1959)
Infrared spectra of polyethylene terephthalate and three of its deuterated analogs have been obtained in the region of 70 to 3600 cm-1, polarized spectra having been obtained down to 330 cm-1. On the basis of analysis of ...
