Tiivistelmä
Deuteron NMR spectra of slowly tunneling ND4+ ions are analysed. Spectra are calculated as functions of the tunneling parameters which are the tunneling frequencies about the symmetry axes C-2 and C-3 of the tetrahedral ion. The structure and splittings within the ground torsional level (GTL) are obtained by fitting the spectra of(ND4)(2)SnBr6. Comparison with the GTL structure obtained before for NH4+ in the same compound gives the isotope reduction factor of the tunneling frequency about 200.
