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

## Abstract The nitrogen NMR shielding of __tert__‐butyl isocyanide (1) is shown to be a sensitive probe of solvent polarizability–polarity, since the shielding is demonstrated to be unresponsive to hydrogen bonding effects between 1 and the solvent. The direction of solvent effects observed is exp

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
