Pulsed 1H nuclear magnetic resonance studies of molecular motion and plastic crystallinity in dodecamethylcyclohexasilane
Abstract
Dodecamethylcyclohexasilane exhibits plastic crystalline behaviour from 77 to 253 °C, with molecular rotation taking place both in the crystalline (<77 °C) and plastic crystalline (>77 °C) phases; activation energies for various molecular motions are reported.
