Natural Abundance Solid State 2H NMR Studies of Phase Transitions in Rotator Phase Solids

Variable temperature natural abundance ²H NMR studies of solid state phase transitions in adamantane, tetrakis(trimethylsilyl)methane (TTMSM), tetrakis(trimethylsilyl)silane (TTMSS) and 2,2-dimethyl-1,3-propanediol (DMPD) are reported; in spite of the low sensitivity associated with natural abundance ²H NMR, this technique is demonstrated as a feasible approach for elucidating changes in molecular dynamic properties associated with the phase transitions in these materials.
