Abstract
15N NMR spectroscopy was used to distinguish between isomers and to characterize some series of novel fused polyaza heterocyclic ring systems. Support for the assignments was provided by means of some INDO/S‐SOS shielding calculations. Previously observed shielding trends, as a function of nitrogen type, are reproduced in the present set of molecules.Keywords
