Nitrogen NMR studies on some fused ring N-heterocycles

Abstract

15N and14N NMR data are reported for a number of fused ring N-heterocycles.14N line widths,15N-1H couplings and nitrogen shielding additivity rales are used for15N signal assignments. The results obtained lead to some progress in the generalization of the effects of nitrogen-nitrogen interactions on nitrogen shieldings.
