N NMR spectroscopy was used to extend previous studies, by "C NMR and IR spectroscopy, of fused oxoheterocycles which contain the guanidine unit. These compounds fall into three clearly definable structural types, through-conjugated, ring-conjugated or imide-like, any or all of which may result from

## Abstract A natural abundance ^15^N NMR study was carried out on a series of 1‐ and 2‐mono‐ and 1,5‐ and 2,5‐disubstituted tetrazoles in different media. An erroneous assignment given in the literature for 2,5‐disubstituted tetrazoles was corrected using MNDO molecular orbital calculations and th
