✦ Synopsis

1,2,3‐Triazabutadienes. XV. Substituent Effects on the Nitrogen‐15 and the Carbon‐13 Chemical Shifts of Triazabutadienes and Azobenzenes

Nitrogen‐15 and carbon‐13 chemical shifts are reported for ^15^N‐enriched p‐substituted triazenes 1, triazenium salts 2 and azobenzenes 3. Linear correlations between substituent induced shifts for various ^15^N‐ and ^13^C‐atoms and σ‐Hammett constants was found and discussed. The sensitivity of the chemical shifts of both nuclei to substituent effects in analogously constituted compounds are compared.
