Selected topics in fast atom bombardment (FAB) mass spectrometry a)specially designed probe tips and ion generation, b)structures of vitamin B6 schiff base complexes
(Brock University, 1988-07-09)
This thesis can be broken down into two sections. Section one is a study . of the ionization mechanisms and the ion source optimization for Fast Atom Bombardment (FAB) ionization. For this study, several specially designed ...
A high resolution study of the 4Â¹â bands of Â¹Â³CHâ O and CHâ Â¹â ¸O
(Brock University, 1977-07-09)
Palladium and platinum complexes of vitamin Bâ
(Brock University, 1982-07-09)
Palladium and platinum complexes of pyridoxamine, pyridoxine and pyridoxal have been prepared. The structures of the complexes PtCI2PM.H20, trans-PdC12 (PN)2 and [PLH+ ]2[PtC16] 2- ,H20 have been determined by use of ...
A time-resolved electron paramagnetic resonance spectroscopy study of paramagnetic porphyrins /
(Brock University, 2004-07-14)
There is considerable interest in intramolecular energy transfer, especially in complexes which absorb visible light, because it is crucial to the better understanding of photoharvesting systems in photosynthetic organisms ...
Synthesis of 4-hydroxycinnamic amides of di-, tri-, and tetraamines : potential insect toxins /
(Brock University, 2000-05-21)
The monoconjugates of phenolic acids (i.e. coumaric acid) with polyamines such as spermidine and spermine are strikingly similar to some toxins from spiders and predatory wasps. Many plants contain phenolic acid ...
Synthesis of photoaffinity analogues of alpha-tocopherol /
(Brock University, 1999-05-21)
Arsenic and germanium determination by hydride generation in the D.C. plasma optical emission spectrometer
(Brock University, 1986-07-09)
Modifications to the commercial hydride generator, manufactured by Spectrametrics, resulted in improved operating procedure and enhancement of the arsenic and germanium signals. Experiments with arsenic(III) and arsenic(V) ...
Investigations into phosphorus removal by constructed wetlands : root bed media modifications /
(Brock University, 1997-05-21)
A study has been conducted focusing on how the phosphorus renrx)val efficiency of a constructed wetland (CW) can be optimized through the selective enrichment of the substratum. Activated alumina and powdered iron were ...
The vibrational spectra and the normal coordinate analysis of thiocarbonye halides /|nby C. R. Subramaniam. -- 260 St. Catharines, Ont. : [s. n.],
(Brock University, 1969-07-09)
The infrared and the Raman spectra of eSelF has been obtained for the first time and has been analysed to give the in-plane normal vibrational frequencies of the molecule, in the ground state. A normal co-ordinate ...
Mass spectral studies of some pentafluorophenyl derivatives of group V /|nby Andrew Tanner Rake. -- 260 St. Catharines, Ont. : [s. n.],
(Brock University, 1970-07-09)
The mass spectra of compounds of t he series (C6F5 )3-n MP~ (n = 1,2,3, M = P and As ), (C6F5>3Sb, Ph) Sb and (C6F5 )2SbPh have been studied in detail and the important modes of fragmentation were e1ucidated, a ided by ...
