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 ...
Vibrational force field and normal mode analysis of N,N-dimethylacetamide
(Elsevier, 1989)
A simple general valence force field has been refined for N,N-dimethylacetamide which includes both in-plane and out-of-plane modes. This force field gives good agreement between observed and calculated frequencies for ...
Vibrational analysis of cyclo(-Ala--Ala) in two crystalline forms. Effect of structure on peptide group and CH modes
(Elsevier, 1988)
Cyclo(-Ala--Ala) has been found by X-ray diffraction to crystallize in two forms with different hydrogen bond patterns and strengths and different conformations of the C[alpha]H[alpha]C[beta]H3 group. We have done a ...
Surface enhanced raman spectroscopy of halide ions on colloidal silver: simulation of silver-halide ion spectra
(Elsevier, 1983-01-02)
The surface enhanced Raman spectra of halide ions adsorbed on colloidal silver surfaces can be explained by an interacting dipole model of a discrete adsorbate superlattice. Both (100) and (111) surfaces have been modeled, ...
Electromagnetic effects on a molecule at a metal surface : I. Effects of nonlocality and finite molecular size
(Elsevier, 1981-08-02)
The electromagnetic effects on a molecule near a metal surface are considered with the view to understanding the surface-enhanced-Raman-scattering (SERS) effect. The image enhancement effect is calculated including the ...
Vibrational analysis of 2,3-dichlorobutanes
(Elsevier, 1983)
Using intensity changes from liquid to solid for meso- and racemic-2,3-dichlorobutanes, and preliminary normal mode calculations based on a force field for secondary chlorides, we have been able to identify the bands ...
Electromagnetic fields in biological studies
(Kluwer Academic Publishers; Pergamon Press Ltd. ; Springer Science+Business Media, 1985-11)
For biological or cellular experiments using electromagnetic fields, it is essential that the parameters defining the field be carefully specified if the results are to be meaningful and are to be compared with the same ...
Studies on the localization of newly added membrane in growing neurites
(Wiley Subscription Services, Inc., A Wiley Company, 1981-11)
Explant culture of the adult goldfish retina results in vigorous neuritic growth, provided that the optic nerve has been previously crushed in vivo. The site of new membrane addition in these growing neurites was studied ...
Shift and broadening of the vibrational mode for a diatomic molecule adsorbed on a metal surface
(Elsevier, 1983-06-02)
The shift and broadening of the vibrational frequency of a diatomic molecule adsorbed on a metal surface are calculated on the basis of electromagnetic interactions. Finite molecular size and nonlocal metal response are ...
Search for cyclotron resonance in cells in vitro
(Wiley Subscription Services, Inc., A Wiley Company, 1989)
There are a number of reports of the plasma membrane transport of Ca 2+ in biological systems being enhanced by low frequency electromagnetic fields (EMF), including reports that the enhancement involves a resonance-type ...
