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. CF spin‐spin coupling constants were determined. Pauling electronegativity values for SO3H and SF5 groups were derived
对 50 多种无环磺酸、碱金属磺酸盐和甲酯的 13C NMR 光谱进行了化学位移分析。建立了以正构烷烃为参考分子的线性烷烃磺酸盐和烷烃 2-烯磺酸盐的化学位移增量系统。还研究了一些短链氟化磺酸,尤其是五氟硫代衍生物。确定了 CF 自旋-自旋耦合常数。SO3H 和 SF5 基团的鲍林电负性值源自 α 化学位移增量。
