## 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
