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, ...
Temperature dependence of the diffusion coefficient of polystyrene latex spheres
(Wiley Subscription Services, Inc., A Wiley Company, 1983-02)
No Abstract.
PVT analysis of a new cubic-perturbed, hard-sphere equation of state
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1983-05)
The cubic-perturbed, hard-sphere equation of state proposed in 1980 by Ishikawa, Chung and Lu, has been analyzed by PVT criteria, as contrasted to the single component and multicomponent vapor-liquid equilibria to which ...
The mechanism of propylene oxidation to acrolein over bismuth molybdate, copper oxide, and rhodium catalysts
(Elsevier, 1983-08)
The oxidation of (E)-propene-1-d1 to acrolein over bismuth molybdate, copper oxide, and rhodium catalysts was studied to determine if the reaction proceeded with (Z)-(E) randomization of the deuterium stereochemistry. Over ...
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 ...
Chemical synthesis of 1-O-alkyl and 1-O-acyl dihydroxyacetone-3-phosphate
(Elsevier, 1983-08)
A method for the chemical synthesis of 1-O-hexadecyl dihydroxyacetone-3-phosphate is described. The synthesis was started with the preparation of O-hexadecyl glycolic acid by condensing 1-iodohexadecane with ethyl glycolate ...
Pseudopotential SCF-MO studies of hypervalent compounds : Part III. I2, IF, IF3 and IF5
(Elsevier, 1983-02)
The (ab initio) effective potential method developed previously has been applied to several molecules in order to establish a basis set and effective potential for iodine and to examine aspects of the potential surfaces ...
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 ...
Polymer-membrane pH electrodes as internal elements for potentiometric gas-sensing systems
(Elsevier, 1983)
The use of polymer-membrane pH electrodes as internal sensing elements for the fabrication of inexpensive ammonia and carbon dioxide gas sensing systems is reported. The pH-responsive polymer membranes are prepared by ...
Theoretical predictions on the response properties of potentiometric gas sensors based on internal polymer membrane electrodes
(Elsevier, 1983)
The appropriate equilibrium expressions and known thermodynamic equilibrium constants are used in calculations on the expected response properties of polymer membrane electrode-based ammonia and carbon dioxide gas sensors. ...
