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.
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 ...
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 ...
Synthesis of 9-carboxymethylcarbazole-substituted polydehydroalanine and poly(dehydroalanine methyl ester)
(John Wiley & Sons, Inc., 1983-03)
No Abstract.
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 ...
Syntheses and polymerizations of some vinyl monomers containing nitro- or fluorophthalimides
(John Wiley & Sons, Inc., 1983-12)
4-Nitro- N -vinylphthalimide ( 4 ) was synthesized by two different procedures. Compound 4 was not polymerizable or copolymerizable by AIBN. Poly( N -vinylphthalimide) ( 17 ) was prepared and partially nitrated at 10–25°C. ...
Grafting of living poly(ethylene oxide) onto polystyrene via aromatic nucleophilic displacement of activated nitro groups
(John Wiley & Sons, Inc., 1983-12)
Polystyrene of M¯ Ω = 2.2 × 10 4 was alkylated with 4-nitrophthalimidomethyl groups as grafting sites. Several backbone polymers with various degrees of grafting sites ( G = 2–100%) were prepared and characterized by ...
