Absolute nitrogen screening constants and chemical shifts of some N-heterocycles are calculated within the CNDO/S level of approximation to Pople's model. Satisfactory agreement between calculated and observed nitrogen chemical shifts is obtained in most cases. The application of the results to the

High-precision 14N NMR measurements of solvent-induced shielding variations are reported for some nitrosobenzene systems. These variations are shown to result from a combination of three major factors, solvent to solute hydrogen bonding where the solute nitrogen lone pair electrons are involved, sol
Results of the first extensive investigation of the nitrogen published work on solvent-induced effects on nitrogen shielding of 1,2,4,5-tetrazine ( I ) are reported. Due attention shieldings is 1,2,4,5-tetrazine: is paid to solvent-induced nitrogen-shielding variations by a variety of solvents. A co
High-precision nitrogen NMR shieldings, bulk susceptibility corrected, are reported for the N-methyl derivatives of the two existing isomeric tetrazoles (I, II) in a variety of solvents which represent a wide range of solvent properties from the point of view of polarity as well as hydrogen bond don
## Abstract High precision ^14^N screening measurements are presented for some nitroalkanes. The screening increases as the dielectric constant of the solvent decreases in all cases considered. The ฮฒ effect on the nitrogen screening is found to be largely independent of solvent, and is thus an intr
