## Abstract High‐resolution ^1^H{^14^N} and proton‐coupled natural‐abundance ^13^C{^14^N} double resonance spectra have been recorded for pyridinium tetrafluoroborate dissolved in CD~3~CN. Iterative analysis of these spectra has provided the accurate values and relative signs of all possible long
## Abstract In order to study the structure dependence of the ^13^C,H coupling constants in polycyclic conjugated π electron systems with 5‐and 7‐membered rings, the ^1^H coupled ^13^C NMR spectra of aceheptylene, azulene and 5‐azaazulene have been analysed. The results are discussed, including pub
