The tetrazole-azide tautomerization of some halogen-substituted tetrazolo [1,5-a]pyridines was examined by IR spectroscopy at ambient temperature and by 1 H, 13 C and 15 N NMR spectroscopy at various temperatures. The tetrazolopyridines can exhibit equilibrium between the azide and the tetrazole for

## Abstract Linear relationships between the inverse of the quadrupolar coupling constant, 1/χ and the asymmetry parameter η are obtained for the ^7^O‐nucleus of acetone oriented in four different nematic phases, using the information contained in ^1^H‐ and ^17^O‐NMR spectra.

## Abstract 5‐Substituted 1,3,4‐thiadiazol‐2(3__H__)‐ones were shown to exist almost exclusively in the oxo tautomeric form with the aid of proton‐coupled ^15^N‐NMR spectra using the corresponding 3‐methyl‐1,3,4‐thiadiazol‐2(3__H__)‐ones and 5‐substituted‐2‐methoxy‐1,3,4‐thiadiazoles as reference c
