    • Aromatic systems containing the perinaphthene nucleus 

      Aitken, I. M. (University of St Andrews, 1958) - Thesis
      This thesis compirses three parts, Parts A, B and C. Each part is divided into a number of principal sections prefixed by Roman numerals, and these sections are further divided into sub-sections prefixed by Arabic numerals. ...

    • Polycarboxylic acids via catalytic hydrocarboxylation of polybutadienes 

      Pondicherry, Narayanan (University of St Andrews, 1992) - Thesis
      Polybutadiene having varying degrees of 1,4 and 1,2 units (0 - 100% cis, 14 - 60 % trans, 20-88 % pendant carbon-carbon double bonds) have been reacted with carbon monoxide in the presence of water and palladium based ...

    • Studies of quenching of excited states of aromatic molecules in polymer matrices 

      Jassim, Alwan Nsayiff (University of St Andrews, 1980) - Thesis
      The phosphorescence behaviour of a series of polycyclic aromatic compounds has been studied in different polymer matrices. Measurements have been carried out at 77K and from room temperature up to 350K. Studies at 77K have ...

    • Some studies of the chemical reactivity of β-lactam antibiotics 

      Robinson, Derek I (University of St Andrews, 1981) - Thesis
      Rate coefficients for the inactivation of several penicillin in acids and alkalis at 30°C have been determined by means of ultraviolet spectroscopy. The case of benzylpenicillin, though well investigated in the past, has ...

    • Some studies in hydride transfer 

      Payne, Henry Arthur Sheldon (University of St Andrews, 1966) - Thesis
      The term “hydride-transfer” is used to describe the acquisition in a single step of a hydrogen nucleus together with a pair of electrons by one electrophilic centre at the expense of another, either in the same or in another ...
