Mature of 'Chlorine Effect' in the ~(17)O NMR Spectra of Sulfur Compounds XSO2Y

摘要

Nature of "chlorine effect" in the ~(17)O NMR spectra of compounds XSO2Y associated with the exclusive influence of chlorine on the position of the signal of terminal oxygen is considered. The effect is found to be determined by the electron population of sulfur 3d orbitals, which reaches maximum in the case of X, Y = C1.
