Abstract: At the explanation of the spectra peculiarities of phenylsulfones by general formula C₆H₅SO₂R the arguments in favour of intramolecular effect of functional groups position in the fragment R through the spatial on the value of phenyl protons chemical shifts ð_i^Hhave been adduced.

Keywords: Key words:NMR 1H spectra of phenylsulfones by general formula C6H5SO2R,basic (diH) and differential (ΔdiH) spectral parameters, main andauxiliary compounds,“threshold” differential parameters,intramolecular effect through the spatial.
