Abstract

Nitrogen‐15 and Carbon‐13 Chemical Shifts and 13 C‐ 1 H, 13 C‐ 15 N and 15 N‐ 15 N Coupling Constants of Parasubstituted Arene Diazonium Salts Nitrogen‐15 and carbon‐13 chemical shifts and 13 C‐ 1 H, 13 C‐ 15 N and 15 N‐ 15 N coupling constants of 15 N‐enriched p‐substituted arene diazonium salts are reported and within the ΔE‐approximation investigated. It is shown that changes of ΔE should be taken into account when considering variation of the nitrogen‐15 chemical shifts. The influence of substituent effects was discussed within the DSP (dual substituent parameter)‐approach.
