 Title    Ionic motion and Disordered Structure in the Rotator Phase of Butylammonium Chloride Studied by Temperature Dependences of 35C1 and 2HNMR  
 Abstract    Temperature dependences o f 35C1 and 2H quadrupole coupling constants and 35C1 N M R spin-lat­ tice relaxation times in polycrystalline samples were measured in the rotator phase of the butylam ­ m onium chlorides C 4H 9N H 3C1 and C4H 9N D 3C1, obtainable above the phase transition tempera­ ture o f 241 K. A rapid decrease o f the quadrupole coupling constants of both nuclei upon heating is attributed to increasing dynam ic disorder formed around the polar head. The presence of self-dif-fussion o f C P ions was revealed from the spin-spin relaxation time and resonance line-width in single crystals, and confirmed by measuring the dc electrical conductivity.
