The Preparation Of The Coordination Compounds Of Palladium (Ii) And Spermine And Spermidine, Wenli Grace Lee

University of the Pacific Theses and Dissertations

The purpose of this study was to prepare and characterize complexes produced by the reactions of spermine and spermidine with palladium(II) chloride. A first analysis of the problem seemed to indicate that preparation of the complexes should be straightforward and not difficult. Bonding of the nitrogen atoms to the metals allows sterically for formation of two six-membered rings separated by a tetramethylene chain in a spermine complex, and by a six-membered chelate ring in a spermidine complex.

A Spectroscopic Study Of Intramicellar Environment With Merocyanine Dye Probes, Elise Jane Daggs

University of the Pacific Theses and Dissertations

The effects of micelle forming surfactants hexadecyltrimethylammonium bromide, sodium dodecyl sulfate and igepal CA~6JO on the visible spectra of merocyanine dyes of the form 1-alkyl-4-[(3', 5'-alkyl oxocyclohexadienylidene)ethylidene]- 1,4-dihydropyridine were studied. In all cases the visible spectrum shifted to the red when the dye was incorporated into the micelles. The magnitude of the shifts was found to be dependent on the substituted groups and the positioning of the chromophore of the dye in the micelle aggregates. The shifts indicate a highly hydrated environment about the surfactant head groups and an environment equivalent to that of pure ethanol solvent at some undetermined …

The Effect Of Tungsten(0)Pentacarbonyl On Coordinated Ligands, Janice Imada Byington

University of the Pacific Theses and Dissertations

A series of monosubstituted tungsten(0)pentacarbonyl complexes, W(CO)₅L (L = water, hydrogen sulfide, pyrazine, pyrimidine, 4,4'-bipyridine, 4-cyanopyridine, isonicotinamide, and methanol) were synthesized and characterized. The purpose of this project was to determine the effect of the W(CO)₅ moiety on the coordinated ligand, L.

The visible spectra of the synthesized W(CO)₅L complexes typically exhibited a maximum around 400 nm ((epsilon) (TURN) 4000). The infrared spectra of these complexes exhibited the characteristic three band pattern (2A₁ + E) in the carbonyl region ((TURN)2070 cm^-1, (TURN)1930 cm^-1, (TURN)1900 cm^-1. The pKa's of …

The Reaction Of 4-Vinylcyclohexene With Palladium (Ii), Kathy Ellen Beeler

University of the Pacific Theses and Dissertations

This program of study was concerned with the elucidation of the causes(s) behind the inability of various workers to reproduce the work of Fyre and Kuljian on the rearrangement of 4-vinylcyclohexene to 1,5-cyclooctadiene by the action of palladium (II).

Flow Injection Atomic Absorption Assay Of Copper And Zinc In The Plasma Of Age Dependent Audiogenic Seizure Susceptible Mice, Neal Dwain Byington

University of the Pacific Theses and Dissertations

Flow injection atomic absorption procedures with less than 10%RSD at 1.0 ppm were developed for the assay of copper and zinc in 10 μL samples of mouse plasma. The flow injection apparatus was designed with a pulseless liquid flow control system, regulated by inert gas pressure. The aspiration liquid is 6% t-butanol in water. After exhaustive parameter optimizations, copper assays were conducted with the conventional air-acetylene flame at 324.754 nm and zinc assays were conducted with the unconventional argon-hydrogen air diffusion flame at 213.856 nm. The argon-hydrogen flame system was chosen because it absorbs very little ultraviolet light.
