Abstract: The data on studying the azido-tetrazole equilibrium in the tetrazoloazine series by using <superscript>15</superscript>N-labeled samples are reviewed. The incorporation of the <superscript>15</superscript>N atom significantly expands capabilities of NMR spectroscopy. An analysis of chemical shifts and <superscript>1</superscript>H—<superscript>15</superscript>N, <superscript>13</superscript>C—<superscript>15</superscript>N, and <superscript>15</superscript>N—<superscript>15</superscript>N spin-spin coupling constants is an efficient method for studying these transformations.
