Phase transition kinetics and reorientational dynamics of the plastic crystal meta-carborane studied by deuteron NMR. In: Journal of Non-Crystalline Solids Jg. 307-310(2002), S. 442-448, doi: 10.1016/S0022-3093(02)01506-5.http://hdl.handle.net/2003/2556510.17877/DE290R-2676Meta-carborane shows an orientationally disordered, orthorhombic phase which transforms into an ordered monoclinic phase near 170 K and into a quasi-isotropic cubic phase near 280 K. From deuteron magnetization measurements both transitions are found to exhibit a thermal hysteresis and slow transformation kinetics. Furthermore, solid-echo NMR spectra and spin-lattice relaxation times are reported. These results indicate that in the orthorhombic phase the meta-carborane molecules perform a strongly anisotropic motion which is characterized by a temperature dependent amplitude.enElsevier Science53010.1016/S0022-3093(02)01506-5article (journal)
