本文从质子核磁共振的化学位移值(τ)出发,建立了一个计算有机官能团电负性(x)的经验公式;x=6.0-0.41τ,计算了一百种常见有机官能团的电负性,并对所得结果进行了简单讨论。
Based on the chemical shift value (τ) of proton nuclear magnetic resonance, an empirical formula for calculating the electronegativity (x) of organic functional groups was established. X = 6.0-0.41τ. The electronegativity of one hundred common organic functional groups was calculated, And a brief discussion of the results obtained.
