## 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
In the ^1^H and ^13^C NMR spectra of selenophene‐2‐carbaldehyde azine, the ^1^H‐5, ^13^C‐3 and ^13^C‐5 signals of the selenophene ring are shifted to higher frequencies, whereas those of the ^1^H‐1, ^13^C‐1, ^13^C‐2 and ^13^C‐4 are shifted to lower frequencies on going from the __EE__ to __ZZ__ isom
