研究了 61 种具有广泛不同取代基的五氟苯基衍生物的氟化学位移和耦合常数。研究发现，两个间位耦合常数与对氟的化学位移形成良好的直线关系，并且认为这些关系主要取决于取代基的电子供体或受体特征。
The fluorine chemical shifts and coupling constants of 61 pentafluorophenyl derivatives with widely varied substituents are examined. It is found that two of the meta coupling constants form good straight line relationships with the chemical shift of the p-fluorine and it is argued that these relationships are mainly dependent upon the-electron donor or acceptor character of the substituent.
