Structural phase transitions and molecular dynamics in organosilicon molecular crystals: A solid state NMR spectroscopic investigation — •Stephan Dusold, Jörg Kümmerlen, and Angelika Sebald — Bayerisches Geoinstitut, Universität Bayreuth

Solid state NMR spectroscopy is a powerful tool for the elucidation of both the structure and the dynamics of molecules in the solid state. A wide variety of one- and multidimensional NMR experiments are available to directly investigate reorientational processes with rate constants ranging from 10−1 to 104 s−1.
The transition from an ordered to a disordered phase is often associated with changes in either the molecular/crystal packing and/or the dynamics of inter- or intramolecular reorientation. In all these cases high resolution solid state NMR spectroscopy can provide direct insight into the phase transition at a molecular level. Here we present results from a 13C and 29Si variable temperature CP/MAS NMR investigation on phase transitions and molecular dynamics in organosilicon compounds Si2R6 with bulky to very bulky substituents R, such as R = tert.−Bu, SiMe3.
