Abstract
The proton nuclear magnetic resonance (NMR) second moment and spin-lat tice relaxation time for polycrystalline bis-n-propylammonium pentabro moantimonate (nPBA) have been measured from 70 to 290 K. The results a re interpreted in terms of the CH3 and NH3 group reorientations for wh ich the activation parameters have been determined. A structural phase transition evidenced at about 220 K is found in the polycrystalline s ample of nPBA.
