Investigation of structural phase transitions in minerals and analogue systems by high-temperature magic-angle-spinning nuclear magnetic resonance spectroscopy

This work comprises studies of structural phase transitions (SPT's) in three different phases (anorthite CaAl;Insight regarding structural changes for all three phases was obtained from the temperature dependence of the chemical shift. In Chapter 1 the temperature variation of the modulation wave in the incommensurate phase of Sr;For anorthite and AlPO...
