✦ Synopsis

The natural abundance =N NMR spectra of sulphamide, sixteen 1,2,6-thiadiazine and two 1,2,4,6thiatriazine derivatives, phenylbutazone and antipyrine have been recorded for the first time. The influence of substitnents on nitrogen chemical shifts and the effect of intercalation of SO, and CO groups between two nitrogen atoms are discussed. Prototropic tautomerism was also studied. "CNMR data for some of the l,f,(i-thiadiazine and tbiatriazine derivatives are reported.

## Abstract ^13^C and ^15^N NMR chemical shifts were measured for __N__^1^‐alkyl‐__N__^2^‐arylthioureas. The absence of decoalescence of the __N__^1^‐alkyl group carbon signals down to 190 K, the europium‐induced chemical shifts and the molecular mechanics calculations indicate that the preferred c
