    • Structural studies of layered perovskites 

      Snedden, Alan (University of St Andrews, 2004) - Thesis
      In 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) 

      Torbet, Alan (University of St Andrews, 1973) - Thesis
      This 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 

      Mitchell, Alan Lyall (University of St Andrews, 1988) - Thesis
      A 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 

      McGregor, Alan (University of St Andrews, 1997) - Thesis
      Investigations 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 

      Said, Ahmed Ahbeil (University of St Andrews, 1970) - Thesis
      Methylricinoleate 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 ...
