## Abstract The variation of the ^15^N chemical shifts with substitution for a series of 1‐aryl‐3,3‐dialkyltriazenes is decribed. Good correlations were found between the relative chemical shifts at all three nitrogen sites and the electronic properties, as measured by the substituent coefficient,

The 15N NMR spectra of the novel seven-membered 1,2,3,5-tetrazepinone ring systems were studied. The chemical shift of N-2 was found to be signiÐcantly responsive to substituent changes at the phenyl ring. As the electron-withdrawing character of the substituents increased, N-2 became more deshielde

## Abstract Substituted 2‐(phenylamino)‐5‐phenyl‐1,3,4‐oxadiazoles were studied by ^15^N NMR spectroscopy. All signals were assigned on the basis of HMQC and HMBC experiments. Chemical shifts values were correlated with empirical Hammett parameters as well as with calculated electron densities and

## Abstract ^13^C, ^14^N and ^15^N NMR data are reported for some mesoionic 2,3‐diphenyltetrazoles with nitrogen‐containing exocyclic groups, and the data confirm their cyclic structures. The protonated forms of these mesoionic structures contain hydrogen atoms at the exocyclic groups.
