Formation and selected reactions of some binuclear oxygen complexes
(1977)
Chelate formation and amide deprotonation reactions of 1:1 cobaltous complexes of glycyl-L-histidine, glycylhistamine, glycyl-L-aspartic acid, L-histidyl-L-histidine, L-histidylglycine, and L-aspartylglycine have been ...
A new method for the simultaneous determination of pyrite content and proximate analysis in coal and lignite
(1983)
Coal Analysis is ordinarily divided into three parts: (1) Proximate analysis, determination of moisture, volatile matter, fixed carbon and ash contents; (2) Ultimate analysis, determination of carbon, hydrogen, sulfur, ...
Characterization of polymerizable surfactant vesicles by nuclear magnetic, absorbance and fluorescence spectroscopy
(1982)
The formation of vesicles and polymeric vesicles from unsaturated surfactants was discussed in regards to conditions for formation (sample size and sonication time), polymerization, substrate entrapment, hydroxide ion ...
The synthesis and characterization of arsenocholine and related compounds
(1982)
It has been known for 80 years, that arsenic is present in marine organisms in form of organic compounds. Only recently have some of these compounds been identified. Arsenobetaine, arsenocarbohydrates and dimethyl(2-hydr ...
Regiochemical and stereochemical studies of cationic pi-cyclizations
(1982)
Cationic (pi)-cyclization of allenyl alcohols 10a,b and allenyl ketones 11a,b provided evidence that the mode of ring closure of (gamma)-allenyl cationic systems is strongly dependent on the substitution pattern of the ...
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 ...
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 ...
Graphite furnace atomic absorption analysis of organotin compounds
(1982)
Direct analysis of organotin compounds by graphite furnace atomic absorption (GFAA) spectrometry is complicated by the presence of chemical interferences that cause a species-dependent sensitivity. To reduce these interferences ...
