| Notes: |
A chemical shift analysis of the 13C NMR spectra of more than 50 acyclic sulphonic acids, alkali metal sulphonates and methyl esters was carried out. Chemical shift increment systems with n-alkanes as reference molecules were established for linear alkanesulphonates and alk-2-enesulphonates. Some short-chain fluorinated sulphonic acids were also studied, especially pentafluorothio derivatives. C—F spin-spin coupling constants were determined. Pauling electronegativity values for SO3H and SF5 groups were derived from α chemical shift increments.
