Structural studies of layered perovskites
(University of St Andrews, 2004) - ThesisIn this work studies have been carried out into the structures of three families of layered perovskite using powder neutron diffraction. It is shown that Bi₅Ti₃FeO₁₅ exhibits only one high temperature phase transition, ... -
A study of the photochemical decomposition of poly(isobutylmethacrylate)
(University of St Andrews, 1973) - ThesisThis present study was undertaken to obtain kinetic data on the photolytic decomposition of poly(isobutlyl-methacrylate) using a new technique of direct weight measurement during the reaction rather than the indirect ... -
A study of ion-molecule reactions in the gas phase using a triple quadrupole mass spectrometer
(University of St Andrews, 1988) - ThesisA triple quadrupole mass spectrometer was used to study a number of different ion-molecule reactions. The TQMS is a relatively new device, and is ideally suited to the study of gaseous ion-molecule reactions. It avoids the ... -
Syntheses and properties of liquid crystalline macrocyclic complexes
(University of St Andrews, 1997) - ThesisInvestigations are conducted into substituted tetraazaannulenes with the objective of forming novel liquid crystalline compounds. Various synthetic strategies are devised and the compounds tested by differential scanning ... -
Some reactions of methyl 12-mesyloxyoleate
(University of St Andrews, 1970) - ThesisMethylricinoleate contains a homoallylic hydroxy group and is therefore a potential source of homoallylic carbonium ions which can undergo an interesting rearrangement and furnish cyclopropane compounds. This thesis reports ...
