Isonitrile derivatives of polynuclear metal carbonyls
Thesis
Isonitrile derivatives of polynuclear metal carbonyls. https://keele-repository.worktribe.com/output/416651

The synthesis of a number of transition metal carbonyl complexes and their isonitrile derivatives has been carried out. The fluxional character of some of the isonitrile substituted derivatives has been studied by means of infrared and variable tempe...

The synthesis of aza-azulene derivatives
Thesis
The synthesis of aza-azulene derivatives. https://keele-repository.worktribe.com/output/416783

Various synthetic routes to the pyrrolo[1,2-a]azepinium system were attempted.
Chapter Two describes the preparation of some 1-azido-3- phenylprop-1-enes. Thermal decomposition of these vinyl azides did not result in any pyrrolo[1,2-a]azepines.
Att... Read More about The synthesis of aza-azulene derivatives.

The molecular beam maser employing quasi-optical resonators: oscillation behaviour and spectroscopic applications
Thesis
The molecular beam maser employing quasi-optical resonators: oscillation behaviour and spectroscopic applications. https://keele-repository.worktribe.com/output/416793

The spectroscopic and oscillation properties of the molecular Beam maser, employing quasi-optical resonators are investigated. A new type of cavity, the roof-top resonator, is introduced for molecular beam work. The theoretical discussion reveals tha...

The Synthesis and properties of [1,2,3] triazolo [1,5-a] pyridines
Thesis
The Synthesis and properties of [1,2,3] triazolo [1,5-a] pyridines. https://keele-repository.worktribe.com/output/416874

Chapter one describes the electrophilic substitution reactions of [l,2,3]triazolo[l,5-a]pyridine, and the reactions in which nitrogen extrusion are characteristic. It also describes the attempts to functionalise the pyridine ring. A review on the syn... Read More about The Synthesis and properties of [1,2,3] triazolo [1,5-a] pyridines.

Synthetic studies on farnesene isomers and homologues from the Dufour glands of ants

Synthetic studies on farnesene isomers and homologues from the Dufour glands of ants. https://keele-repository.worktribe.com/output/416979

(Z,E)-q-farnesene and its homologues homo-, bishomo- and trishomo-farnesenes had been identified as constituents, of the Dufour gland secretion of several species of Myrmica ant. Although farnesene isomers had been found previously in plant and insec... Read More about Synthetic studies on farnesene isomers and homologues from the Dufour glands of ants.

The application of code conversion techniques to digital audio systems
Thesis
The application of code conversion techniques to digital audio systems. https://keele-repository.worktribe.com/output/416982

The recent development of low cost digital storage has made digital audio systems attractive. However its popularity depends on the development of accurate low cost digital to analogue (D/A) converters. Existing converters require the fabrication of...
