Investigation of the protolytic equilibria of nitraminotetrazoles in aqueous media

The UV and Raman spectra of a number of nitraminotetrazoles were recorded in aqueous media. The dependence of the spectral characteristics on the pH and H_o was studied, and the dissociation constants of neutral and protonated molecules were determined. It was established that 5-nitramino- and 1-methyl-5-nitraminotetrazole exist in the nitrimine form in aqueous solutions.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1569–1571, November, 1984.
