摘要
运用中性原子价层轨道能和电负性均衡原理 ,建立了一个新的计算中性基团电负性的公式 : EG=Πmj=1 [Πni=1 (-Ei)niΣn]mjΣm运用该式计算了 2 58个中性基团的电负性 ,计算结果与国内外新近的几套基团电负性颇为一致。
By using the energy of va1ence orbits in the neutra1 atom and princip1es of e1ectronegativity equa1ization,a new formu1a for the ca1cu1ation of neutra1 group e1ectronegativities has been obtained: G= Π m j=1 [ Π n i=1 (-E i) n i Σ n ] m j Σ m The group e1ectronegativities for 258 common neutra1 groups have been ca1cu1ated.The resu1ts of the present study agree quite we11 with the severa1 sets of group e1ectronegativities pub1ished in 1iteratures recent1y.
