Empirical equations for 13C NMR chemical shifts of alkanesulfonic acids.
BUNSEKI KAGAKU, 1984 13C 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 electro ...
