## 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

Rates of rotations about the C-N' partial double bond in a series of six N',N' penta-and six N',N'-hexa-methylene-Nz-substituted-phenyformamidines were determined from 13C DNMR line shape analysis. Electron accepting substituents at the phenyl ring increase the barrier to rotation, and electron don
