 Title    Nuclear Quadrupole Interaction and Ionic Dynamics in Sodium Superionic Conductors  
 Abstract    Recent work on the 23N a quadrupole interaction in the N A SIC O N family is reviewed. The applicability and the lim itation of the two-dim ensional nutation N M R to complex systems with more than one quadrupolar nuclear sites is discussed and the possibility of sodium ion exchange in som e of the N A SIC O N -type com pounds is pointed out. The microscopic mechanism of the site exchange is examined by m olecular dynamics simulation. A model potential energy function for the site exchange and /or hopping transport o f the sodium ions is proposed. It interprets qualitatively the difference between the activation energies deduced by N M R and by conductivity measurement.
