Thermochemistry of some platinum and palladium compounds
Thesis
(1978). Thermochemistry of some platinum and palladium compounds

Enthalpies of reaction, at 298 K in the liquid phase have been measured using isoperibol reaction calorimetry, and some enthalpies of isomerisation have been measured using differential scanning calorimetry.
The enthalpy of formation of crystalline... Read More about Thermochemistry of some platinum and palladium compounds.

Studies on ionic polymerisation
Thesis
(1978). Studies on ionic polymerisation

The reaction between anionic polystyrene and cationic polyTHF has been examined and shown to result virtually quantitatively in coupling of the two polymers. The reaction has been exploited to prepare AB, ABA and (AB)n block copolymers and g.p.c. ana... Read More about Studies on ionic polymerisation.

Rearrangement and cycloaddition routes to novel heterocyclic systems
Thesis
(1978). Rearrangement and cycloaddition routes to novel heterocyclic systems

Part I of this thesis describes the treatment of tetrahydro-4-oxoisoxazolo[2,3-alpyridinium, phenyl hydrazone (70) with boiling acetic anhydride to give pyrazolo [4,3-b]pyridine (75) and the pyrrolo[3,2-b] pyridone (74)» or on longer heating, further...

Double beam ammonia maser operated with an open resonator
Thesis
(1979). Double beam ammonia maser operated with an open resonator

The construction of a double beam ammonia maser employing an open resonator of advanced design is described. The operation of this maser as an oscillator permitted a strong oscillation to be obtained which has led to the observation of several novel...

Quantitative: microspectroscopic studies of DNA-drug complexes
Thesis
(1979). Quantitative: microspectroscopic studies of DNA-drug complexes

The interactions in solution and in.the fibre state of the trypanocidal phenanthridine drugs, ethidium bromide, dimidiura bromide and prothidium (di)bromide with DNA have been investigated using a variety of physical techniques. A number of analytica... Read More about Quantitative: microspectroscopic studies of DNA-drug complexes.

Synthetic approaches to nitrene precursors
Thesis
(1979). Synthetic approaches to nitrene precursors

Chapter One describes the search for a synthetic route to 2-azidodiphenylmethanes and 2-azidotriphenylmethanes carrying electron withdrawing substituents in the 4'- and 4W- positions. Extensive use is made of the new Grignard reagent, 4~(1,3-dioxan-2... Read More about Synthetic approaches to nitrene precursors.

Gas chromatographic analysis of ecdysteroids in the desert locust Schistocerca gregaria
Thesis
(1979). Gas chromatographic analysis of ecdysteroids in the desert locust Schistocerca gregaria

The ecdysteroids present in 3rd, 4th, and 5th instar Schistocerca gregaria phase gregaria, and 5th instar Schistocerca gregaria, phase solitaria have been determined by gas chromatography with electron capture detection of their trimethylsilyl ethers...
