✦ Synopsis

Solvent effects on nitrogen shieldings are shown to vary from almost zero to about 26 ppm. These shielding variations can be analysed in terms of a variety of hydrogen bonding interactions and non-specific solute-solvent interactions. Steric effects are also taken into account. The non-specific interactions are found to be well accounted for by INDO/S-SOS shielding calculations incorporating the solvaton model. Nitrogen NMR is shown to be very suitable for distinguishing between a variety of solute-solvent interactions.

High-precision 14N NMR shielding data are reported for 2-methyl-2-nitrosopropane and its azodioxy dimer in a variety of solvents. A range of about 30 ppm, as a function of solvent, is observed for the nitroso nitrogen atom. This contrasts with the corresponding shielding range for the dimer, which i

## Abstract Intermolecular effects are shown to induce a variation of about 5 ppm in the nitrogen NMR shieldings of aromatic nitro groups. The latter turn out to be comparable to those exerted by substituents in nitrobenzene derivatives in solutions in a given solvent. Substituent effects on the NO
