Abstract
Deuteron NMR spectra of slowly tunneling ND4+ ions are analysed. Spect ra are calculated as functions of the tunneling parameters which are t he tunneling frequencies about the symmetry axes C-2 and C-3 of the te trahedral ion. The structure and splittings within the ground torsiona l level (GTL) are obtained by fitting the spectra of(ND4)(2)SnBr6. Com parison with the GTL structure obtained before for NH4+ in the same co mpound gives the isotope reduction factor of the tunneling frequency a bout 200.
