Jk. Jung et al., NA-23 NMR AND N-14 NQR IN MIXED-CRYSTALS NA1-XAGXNO2, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 53(6-7), 1998, pp. 595-598
The Na-23 (I = 3/2) NMR powder pattern for the m = 1/2 <-> m = -1/2 tr
ansition, broadened by the second-order quadrupole interaction, was in
vestigated in mixed crystals Na1-xAgxNO2 (x less than or equal to 0.16
). From the intensity loss of the Na-23 NMR line caused by the Ag+-imp
urity, the range of the quadrupole interaction in the Na-23 NMR centra
l line was estimated. The range comprises ionic charges approximately
up to the first nearest neighbour Na+ site from the Na-23 nucleus, sho
wing a large difference compared with that obtained from the N-14 NQR
investigation in the same system.
