## 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

## Abstract We have performed ab initio molecular orbital calculations on 1‐ and 2‐substituted propenes, acetaldimines, and aldehydes — H~3~CC(X)=Y and XCH~2~CH=Y (Y = CH~2~, NH, O; X = H, CH~3~, NH~2~, OH, F) — to investigate the effects that substituents and functional groups have on their isoele
## Abstract The ^13^C NMR spectra of six hydroxybenzenes, all chlorobenzenes, all chlorophenols and eight chlorocatechols are measured and assigned. The additivity of the substituent effects and the usefulness of some corrective parameters are studied with regression analysis. The order of the chem
