Abstract

Recent work on the 23N a quadrupole interaction in the NASICON family is reviewed. The applicability and the limitation of the two-dimensional nutation NMR to complex systems with more than one quadrupolar nuclear sites is discussed and the possibility of sodium ion exchange in some of the NASICON-type com pounds is pointed out. The microscopic mechanism of the site exchange is examined by molecular 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 NMR and by conductivity measurement.

Keywords : Nutation NMR; Quadrupole effect; Superionic conductor; NASICON; Chemical ex­change; Molecular dynamics
