The H-1, C-13 and N-15 NMR spectra of several N- and C-vinyltetrazolium salts have been recorded and the observed chemical shifts together with the data of quantum-chemical calculations have been used for evaluation of electronic structure of the investigated substances and selectivity of the exhaustive alkylation of 1,5- and 2,5-substituted tetrazoles.
