The structure of polyacrylonitrile based carbon fibres as studied by electron spin resonance and other electronic properties
Thesis
Assabghy, F. Y. I. (1970). The structure of polyacrylonitrile based carbon fibres as studied by electron spin resonance and other electronic properties

In view of their recently acquired technological importance, the structure and properties of carbon fibres are currently receiving considerable attention. Although the use of electron spin resonance (CSR) in the study of carbons and graphites has lon...

The mobility of electrons in hydrogen at low pressures being a thesis on the motion of electrons in pure hydrogen at moderate values of E/p
Thesis
Bedford, D. K. (1970). The mobility of electrons in hydrogen at low pressures being a thesis on the motion of electrons in pure hydrogen at moderate values of E/p

Measurements of the electron drift velocity at room temperature in pure molecular hydrogen have been made for the E/p range between 40 and 360 volts.cm-1 .torr-1. Experimental conditions were arranged to minimalise the effects of space charge distort...

Studies on novel macrocyclic sulphur compounds
Thesis
Braunton, P. N. (1970). Studies on novel macrocyclic sulphur compounds

This thesis describes the synthesis and properties of 2,2'-­bridged biphenyls in which sulphur or oxygen functions are incorporated into the bridging unit. Seven-, eight-, nine-, ten­- and eleven-membered ring systems were prepared by nucleophilic su... Read More about Studies on novel macrocyclic sulphur compounds.

Electron paramagnetic resonance studies of 3d3 ions in magnesium oxide
Thesis
Codling, A. J. B. (1970). Electron paramagnetic resonance studies of 3d3 ions in magnesium oxide

This thesis reports some electron spin resonance spectra of v2+ and cr3+ ions in magnesium oxide. Chapters I and II describe the basic features of electron paramagnetic resonance and its application to transition metal ions in insulating crystall...

Rearrangements of quinolizinium-1-diazonium salts and related reactions
Thesis
Davies, L. S. (1970). Rearrangements of quinolizinium-1-diazonium salts and related reactions

The methods of synthesis and known properties of aminoquinolizinium compounds are reviewed. A number of 1-aminoquinolizinium salts when treated with aqueous nitrous acid undergo rearrangement. Investigation by degradation and synthesis showed the... Read More about Rearrangements of quinolizinium-1-diazonium salts and related reactions.

Thesis
Good, R. H. (1970). Synthesis and reactions of oxazolopyridinium salts and related heterocyclic systems

2-Substituted oxazolo[3,2-a]pyridinium salts have been synthesised starting from the appropriate

Selected reactions of photo-excited carbonyl compounds in the liquid phase
Thesis
Holmes, J. D. (1970). Selected reactions of photo-excited carbonyl compounds in the liquid phase

The work presented in this thesis falls into two parts; firstly, a study or the cis-trans isomerisation or methyl tiglate (trans 2-carbometho:xy-2-butene) and secondly, a study or the quenching of the Norrish Type II reaction by cyclohexene. Both set... Read More about Selected reactions of photo-excited carbonyl compounds in the liquid phase.

Studies related to the polymerisation of styrene by perchloric acid
Thesis
Mathias, E. (1970). Studies related to the polymerisation of styrene by perchloric acid

The interaction of styrene with HCl04 has been studied in CCl4, CHCl3, CH2Cl2, EtN02 and PhN02. No polymerisation occurs in CCl4 at 0 degrees. The polymerisation in CHCl3 at 0 degrees, -30 degrees and -60 degrees is complicated by side reactions o... Read More about Studies related to the polymerisation of styrene by perchloric acid.

Vibrational energy transfer processes in gaseous systems at high temperatures
Thesis
Millward, G. E. (1970). Vibrational energy transfer processes in gaseous systems at high temperatures

A study has been made of the rate of vibrational excitation in shock heated CO for the temperature range l300K - 2500K, by observation of the infrared emission behind the incident shock wave. Care was taken to eliminate'impurity effects and the non u... Read More about Vibrational energy transfer processes in gaseous systems at high temperatures.
