The azomethine proton chemical shift of thirteen para-substituted neutral Schiff bases, XC 6H 4CH NC 6H 4Y, has been determined in DMSO. Excellent correlation of the chemical shifts of azomethine group with Hammet σ p constants was obtained for substituents in the benzaldehyde moiety. The lack ...

The spectral changes in the Lα2, Lα1, Lβ1, Lβ4, Lβ3, Lβ2, 15, and Lγ1 lines were measured for various compounds of tin and antimony using a two-crystal X-ray spectrometer. The chemical shift was observed in the Lβ2, 15 and Lγ1 lines depending on different oxidation...
DMSO the water is already stronglyhydrogen-bonded tothe solvent, and solutes have only anegligible effect on its chemical shift. This is also truefor D2O; the chemical shift of the residual HDO is verytemperature-dependent (videinfra) but, maybe counter-intuitively, remarkably solute (and pH) ...

aromatic protons (H-2 and H-4) was not sufficient reason for 1, 3, 4-trisubstituted assignment. Besides, chemical shift of -OH in DMSO-d6might be a characteristic for 3-methoxy-4-hydroxy substituted (caδH8.7) and 3-methoxy-5-hydroxy substituted (caδH9.3) in aromatic ring....

shift reagents, spectra with complex, overlapping groups of lines are often disentangled. Before the advent of high field NMR, such spectral simplification as an aid to analysis was probably the most common purpose for using shift reagents. Currently, shift reagents are employed primarily to obtain...
