Abstract
~N(CGN) = dz(23.1 f 1.4) PN 'f (6.8 f 2.2) pc (Rieger and Fraenkel)a3 The nitrogen couplings calculated from the former equation agree better with the observed values and are well within the established error limits of the equation. The magnitude of the heterocyclic nitrogen coupling is presumed to depend on the spin densities on the nitrogen and on its neighboring carbon atoms. QC c ~ ... (33) P. H. Rieger and G. K.
