浅议Mills规则与螺旋理论

Mills Rule and Helix Theory

运用螺旋理论分析了几个化合物的构型及其旋光性关系，解释了Ｍｉｌｓ规则，结果表明，螺旋结构的旋光度大小与其构成螺旋的原子或原子基团的电子可极化性有关，可极化性越大，旋光贡献也越大。螺旋理论不仅可以推断符合Ｍｉｌｓ规则的化合物的构型，也可以推断出不符合Ｍｉｌｓ规则的化合物的构型。螺旋理论与Ｍｉｌｓ规则是一致的。螺旋结构是导致物质具有光学活性的根本原因。

The Mills rule is interpreted by the helix theory by means of analysing the relationship between configuration and rotation of some compounds. The results show that the rotation of helical structure is relevant to the electron polarisability of the atom or atom group that constituted it. The more is the degree of its polarition, the more is its contribution to the degree of rotation. The helix theory can predict the configuration of the compound that conform to or not conform the Mills rule. The helix theory is consistent with the Mills rule. The substantial helicial structure is the essential reason that cause its optical activity.
