Gk. Semin et al., Manifestation of electron-nuclear motions in the Sb-123 NQR spectra of pentafluoroantimonites, RUSS CHEM B, 47(10), 1998, pp. 1933-1934
A dependence between the quadrupole coupling constants (e(2)Qq(zz)) and the
asymmetry parameters of the electric field gradient (eta) for the antimony
atoms in the complex [SbF5](2-) anions of M2SbF5 pentafluoroantimonites (M
= Na, K, Rb, Cs, NH4, Tl, and Et2NH2) was revealed from the Sb-123 NQR spe
ctra at 77 K.
