NMR study of structure and mechanisms of superabsorbent polymers
(University of St Andrews, 1999) - ThesisCommercially important superabsorbent polymers are crosslinked polymers of partially neutralised acrylic acid which can typically absorb and retain up to a hundred times their own weight in water. Superabsorbent polymers ... -
Spectroscopic properties of some lanthanide 𝛽-diketoenolates
(University of St Andrews, 1973) - ThesisThe temperature dependence of the ⁵D₄ Tb ³⁺ level in crystalline Tb(dpm)3 has been determined and its anomalous behaviour has been interpreted in terms of thermal depopulation to a low lying triplet level in the solid ... -
Some studies of aromatic iodination and deiodination
(University of St Andrews, 1973) - ThesisKinetics of the iodination of a number of substituted benzenes and thiophenes by iodine and nitric acid in acetic acid solution have been studied. The reaction is catalysed by dinitrogen tetroxide and hydrogen ions and ... -

A nuclear magnetic resonance study of the metal-nonmetal transition in arsenic-doped germanium
(University of St Andrews, 1977) - ThesisAn investigation of the metal-nonmetal transition in arsenic-doped germanium (Ge;As) has been performed using the technique of nuclear magnetic resonance. The host Ge⁷³ resonance has been observed in twelve, single crystal, ...
