    • Optical properties of metals at low temperatures 

      Baird, David C. (University of St Andrews, 1953) - Thesis
      The work to be described deals with the reflectivity of metals at temperatures down to 20K. A historical introduction shows how the development of electronic optical theory led to an understanding of many of the important ...

    • The radiative heating of plane-parallel and spherical atmosphere 

      Morgan, David H. (University of St Andrews, 1973) - Thesis

    • Nuclear magnetic resonance in some hydrocarbons at low temperatures 

      Lawrenson, Ian J. (University of St Andrews, 1958) - Thesis
      The nuclear resonance absorption spectrum of several hydrocarbons has been studied at temperatures down to 20°K, using the bridge method of detection. A special cryostat was constructed for use with liquid hydrogen. In the ...

    • Non-radiative transitions 

      Robertson, Neil (University of St Andrews, 1977) - Thesis
      This thesis describes theoretical research into multiphonon non-radiative transitions in solids. These processes occur when an impurity centre electron which has been raised to an excited state returns to its ground state ...

    • The effect of local field corrections on the transport properties of solids 

      Saglam, Mesude (University of St Andrews, 1977) - Thesis
      The purpose of this work is to investigate local field type corrections to electrical transport properties and in particular small polaron hopping conductivity. The question of local field corrections to transport properties ...
