15N- und 13 C-NMR-chemische Verschiebungen sowie 13C-1H-, 13C-15N- und 15N-15N-Spin-Spin-Kopplungskonstanten para-substituierter Benzendiazoniumsalze

Nitrogen-15 and Carbon-13 Chemical Shifts and ¹³C-¹H, ¹³C-¹⁵N and ¹⁵N-¹⁵N Coupling Constants of Parasubstituted Arene Diazonium Salts Nitrogen-15 and carbon-13 chemical shifts and ¹³C-¹H,¹³C-¹⁵N and ¹⁵N-¹⁵N coupling constants of ¹⁵N-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.
