The nature of the transition-metal carbonyl bond and molecular orbital calculations and ultraviolet photoelectron spectroscopy of hydrido transition-metal carbonyl clusters
(1981)
The interaction coordinates of chromium hexacarbonyl were quantitatively predicted by the overlap populations from Fenske-Hall molecular orbital (FHMO) calculations. The trans effect, in the interaction coordinates, was ...
The characterization and catalytic activity of molybdenum-Y zeolites
(1982)
The characterization of several molybdenum zeolites was facilitated using X-ray photoelectron spectroscopy. Samples prepared from the reaction of Mo(CO)(,6) with ultrastable zeolites exhibited superficially high concentrations ...
Reactions of lithium alkylalkenylamides
(1984)
The reactions of three lithium dialkylamides derived from N-alkyl-2-allylcyclohexylamine with several substrates which were potential one-electron acceptors were studied. These substrates were benzophenone, (E)-2-tert-bu ...
Speciation through evolved gas analysis using spectroscopic detection techniques
(1984)
Methods utilizing thermal separation and atomic emission detection which are capable of speciating inorganic compounds in solid samples are described. Inorganic samples are gradually heated to 2300(DEGREES)C in a graphite ...
Physical chemical characterization of amphiphilic vesicles and drug entrapment therein
(1978)
Liposomes and surfactant vesicles were characterized as potential drug carriers in this work. Iodide ion permeabilities, extent of drug entrapment and leakage were determined for liposomes. The chemically simpler, although ...
Fluorescence of coronene
(1978)
A search was made for dual fluorescence in deoxygenated solutions of 1,2,3,4-dibenzanthracene and 1,2,5,6-dibenzanthracene in EPA and n-heptane at 77°K. A nitrogen laser was utilized for excitation and a boxcar average ...
The origin of magnetite in carbonaceous chondrites
(1982)
The content and distribution of magnetite in carbonaceous chondrites is of particular interest since it is a substantial component in these, the most primitive materials surviving from solar system formation. Previous ...
Multi-dimensional analyses of large amplitude vibrations
(1982)
Computational methods were developed for correctly calculating the reduced masses for the ring-puckering and ring-twisting vibrations and for calculating the kinetic energy expansions for ring-puckering vibrations. Computer ...
A total synthesis of racemic trichodiene
(1984)
A highly stereoselective, convergent synthesis of ( )-trichodiene was developed using a Lewis acid catalyzed Nazarov cyclization to form the adjacent quaternary centers with the correct stereochemistry. The dienone ...
Synthesis, structure, and reactivity of polynuclear group VI metal complexes
(1984)
Only in the past decade have trimers of the early transition metals been observed. In these clusters the metal atoms are in their higher oxidation states and are bound to simple electron donating ligands. Compounds of this ...
