## Abstract The synthesis and assignment of ^15^N and ^13^C NMR signals of the 1,3,4‐oxathiazol‐2‐one ring in a series of __para__‐substituted 5‐phenyl derivatives are reported. DFT calculations of ^15^N and ^13^C chemical shifts correspond closely to observed values. Substituent effects are interp
