Becently mrrh attention has been paid to the bond or rubstituent diamagnetic anisotropy effect on proton nmr chemical shift(2). In estimating the long-ranBe diamagwtic anisotropy effect, McConnell88 equation( ), bani = CAx(1 -3cor20)3/ 3x3 , has frequently been used and scassttis a satisfactory agre
## 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 ^1^H NMR spectra of 26 substituted chalcones (3βarylβ1 phenylβ2βpropeneβ1βones and 1βarylβ3βphenylβ2βpropeneβ1βones) have been studied. The chemical shifts of the Ξ± and Ξ² protons to the carbonyl group were correlated with Hammett sΜ parameters. To gain information on the effect of the t
