title: Nuclear magnetic resonance proton dynamics study of [N(CH3)2H2]3Bi2I9 at low temperature.
abstract: The phase transitions of dimethylammonium nonaiododibismuthate [N(CH3)2H2]3Bi2I9 were studied by investigating the temperature dependence of the line widths and proton spin-lattice relaxation times in the nuclear magnetic resonance spectrum. Two phase transitions appeared to be connected with motions of the cationic and CH3 group in the molecule, while the third one seemed to be connected with the dynamics of the Bi2I9 group.
