Synthetic and mechanistic approaches to macrocyclic polystannanes
(1980)
The purpose of this study was to synthesize a macrocyclic polystannane, 8, which would potentially use the Lewis acid character of several tin atoms to create an acidic solvation ring similar to the basic ring of the crown ...
Two-dimensional fluorescence spectroscopy : image analysis techniques and applications in bacterial identification
(1985)
Two-dimensional fluorescence spectroscopy is a technique whereby fluorescence spectra are recorded in matrix format as a function of excitation and emission wavelengths. This data format is very useful for the examination ...
Californium-252 plasma desorption mass spectrometry of chlorophylls and chlorophyll aggregates
(1980)
[^252]Cf-plasma desorption mass spectrometry is shown to be an excellent method for the analysis of chlorophylls in aggregated states. Investigation provide experimental evidence for the view that chlorophylls can be ...
Synthesis and NMR studies of substituted spiro[5,5]undecanones and derived bicyclic compounds
(1980)
A detailed study has been made into the preparation, structure, and characterization of a series of arylspiro[5,5]undecanones and derived compounds. This family of spiroundecanones is exemplified by the parent structure, ...
The photochemistry of bicyclo[3.1.0]hexanones, pyrrolinium salts and pyridinium salts
(1980)
The gas-phase photodecarbonylation and photofragmentation reactions of substituted bicyclo[3.1.0]hexan-3-ones have been studied in detail. Photolysis of these ketones yields 1,3-dienes, vinylcyclopropanes and 1,4-dienes ...
The design and synthesis of a model of protein supersecondary structure : the beta barrel
(1980)
A new synthetic approach to the study of protein structure is presented. I have designed a modular protein sequence which might be expected to fold into a structure resembling a β barrel. The design takes into account many ...
Characterization of active sites and the effect of reduction and metal promoters on iron catalysts
(1989)
Infrared spectroscopy has been used as the principal method of characterizing the adsorption sites of iron-based catalysts. Nitric oxide and carbon monoxide were used as probe molecules to observe the effects of reduction ...
