## 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
