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
