摘要
以核磁共振谱的质子化学位移为依据，提出了一个计算基团Ｐａｕｌｉｎｇ 电负性的方法。给出了基团Ｒ 的电负性值与ＣＨ３ —Ｒ 中质子化学位移δ的关系式：ｘ ＝ １０ ．６５ － ８ ．５５５２ － （１．
According to the proton chemical displacement in the NMR spectrum,a method of calculating the Pauling group electronegativity was put forword. The relationship formula between the electronegativity of group R and the proton chemical displacement in CH 3-R has been given: x=10.65-8.555 2-(1.25δ) 2
