Ab initio quantum chemical calculations for unusual d1 niobium complexes, bond stretch isomers, and molybdenum oxo-transfer enzymes
(1995)
Previous interpretation of the EPR spectra of the dl pseudo- D4h NbCI4(PR3)2 complexes assumed that the unpaired electron resides in the b2g(dxy) orbital. In contrast, simple molecular orbital considerations suggest that ...
Discrete and condensed metal cluster compounds : solution and solid state investigations
(1995)
This dissertation presents experimental work in the area of
Enantiomer separations by preparative gas chromatography : theory and practice
(1995)
Gas chromatography was investigated as a preparative method
Vibrational potential energy functions and conformations of 3-cyclopenten-1-one, tetrahydrothiophen-3-one, and tetrahydrofuran-3-one in their electronic excited states
(1995)
The jet-cooled fluorescence excitation spectrum of 3- cyclopenten-l-one has been recorded in the 308-330 nm region, and the electronic origin for the SI(n,7r) state was observed at 30229 cm-'. The observed spectrum consists ...
Synthesis of new chiral gas chromatographic stationary phases with novel selectivities
(1995)
Both linear and cyclic carbohydrates were explored for their
Characteristics of a glucose matrix in 252 Cf-plasma desorption mass spectrometry
(1995)
The use of glucose film as matrix for 252CF-plasma
Sulfur/oxygen chemistry in metal-bound thiolates
(1995)
diazacyclooctane, bme-daco, shows its versatility in
Identification and characterization of the CO Oxidation/CO2 reduction site of Ni-containing carbon monoxide dehydrogenases
(1995)
The active site for the CO Oxidation/CO2 reduction activity of carbon monoxide dehydrogenase, called the C-cluster, consists of a Fe4S4 cluster bridged to a Ni ion. One of the irons, called FCII, is either 5 or 6 coordinate ...
Design and evaluation of magnetic resonance experiments for catalysis
(1995)
The focus of this research was to develop and evaluate new experimental methods for NMR studies of catalysis with a mandate for the use of magic angle sample spinning for all techniques. As a part of this effort several ...
Investigation of solid acidity in zeolites by nuclear magnetic resonance
(1995)
The nature of Bronsted acidity in zeolite catalysts was investigated by several in situ NMR experiments. The proton sites were directly observed by IH-MAS NMR experiments. Dynamics of the zeolite protons were invested ...
