• ^<13>C NMR data of eleven sodium alkanesulfonates in deuterium oxide have been obtained. Simple equations for prediction of chemical shifts have been derived. Maximum deviation between observed and predicted values is ± 0.8 ppm. Substituent effect of sulfonate group on α-carbon is much larger than the degree predicted by linear relationship with electronegativity of 1-substituted alkanes. On the other hand, β-effect is not much variable with kinds of substituents, but comparatively smaller effect is found for sulfonate group. Thus the difference between the effect on α and β-carbon caused by sulfonate group is larger (about 36ppm), which is contrasted with the effect of, for example, methyl group (〜0 ppm).
