- W2041384632 abstract "The Pople theory of chemical shift has been employed to present a theoretical interpretation for observed nitrogen chemical shifts. In the absence of low-lying n→π* transitions which give rise to a large paramagnetic shift, the shielding of nitrogen, as predicted by theory, arises primarily from: (1) the electron density on nitrogen; (2) the mean-excitation energy; and (3) the effect of multiple bonds of nitrogen. A theoretical expression was also derived for calculations of nitrogen chemical shifts in heteroaromatic molecules. It was found that the chemical shifts of the diazines depend on both the pi- and sigma-electronic distributions on the nitrogen atoms. The variations in the nitrogen sigma-electronic densities estimated from chemical shift data are in reasonable agreement with those observed in nuclear quadrupole resonance studies." @default.
