用电负性均衡法计算了97个含重键基团的电负性。虽然这些值似乎是自洽的，但与原子电负性相比，电负性更强的基团的值似乎相当高。本文讨论了这一问题，并得出结论：电负性均衡化的假设是对基团内部极性的一种过于简化的解释，虽然这种解释是有用的。所用的方法是从最近的工作可变电负性。2通过将电负性视为电荷的线性函数，
The electronegativities of 97 groups containing multiple bonds have been calculated by the method of electronegativity equalization. Although the values seem to be self-consistent, those of the more electronegative groups appear rather high in comparison with atomic electronegativities. This problem is discussed and it is concluded that the as-sumption of electronegativity equalizations is an oversimplified, though useful, descrip-tion of the polarity within the group.In a previous paper, 1 the assumption of electronega-tivity equalization was applied to the problem of the calculation of the electronegativity of-bonded groups. The method utilized was developed from recent work on variable electronegativity. 2 By treating the elec-tronegativity as a linear function of charge,
