## Abstract ^15^N NMR chemical shifts of 2‐aryl‐1,3,4‐oxadiazoles were assigned on the basis of the ^1^H–^15^N HMBC experiment. Chemical shifts of the nitrogen and carbon atoms in the oxadiazole ring correlate with the Hammett σ‐constants of substituents in the aryl ring (__r__^2^ ≥ 0.966 for N ato
## Abstract ^13^C and ^15^N NMR spectra of eight substituted 1,2,4‐triazines were measured and assigned. The assignments of the ^13^C NMR spectra were based on the substituent chemical shifts and ^__n__^__J__(C,H) coupling constants. ^15^N NMR chemical shifts generally showing well separated ranges
