| Abstract: | The 13C-{1H} and 119Sn-{1H} NMR spectra of hexaethyldistannane were measured and analyzed using an iteration program for the calculation of the complete line shape with correction of a residual inhomogeneity of the magnetic field and phase distortions. Signals of 22 isotopomers containing magnetic isotopes of tin and carbon in different pairwise and triple combinations were identified, and their spectral parameters were determined. The content of isotopes 119Sn, 117Sn, and 115Sn in the molecule was determined with a high accuracy sufficient for the study of isotope effects in chemical reactions.__________Published in Russian in Izvestiya Akademii Nauk.
