Solid state 13C NMR and phase transitions in hydroxyadamantanes

Abstract

The phase transitions within solid 1-hydroxy- and 2-hydroxyadamantane have been studied using solid state 13C NMR spectroscopy at different temperatures. The values obtained for the phase transitions for the compounds were comparable but much less precise than those reported using differential thermal analysis (DTA) techniques. Disordered solids such as adamantane derivatives appear to be amenable to such solid state NMR analysis. It is most likely, however, that in general the additional use of cross polarization/magic angle spinning will be required.
