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