摘要
旋光性不是由手性决定的,因为手性是人为抽象出的一种概念。手性概念无方向,也无形状、大小、长短等,没有任何参数可以描述它。因此,手性和旋光方向、旋光度大小不可能有任何关系。螺旋结构不是概念而是实体,它有明确的方向性,有许多参数可以描述它。螺旋结构才是导致旋光性的根本原因。螺旋结构与旋光方向和旋光度大小可以联系在一起。螺旋结构本身也是手性的,它与手性论不矛盾。
The optical activity of a molecule is not determined by its chirality. The chirality is an abstract concept, it has neither definite direction nor shape, size and length. There are not any specific parameters to describe the chirality. The chirality, consequently, can not be correlated with the rotatory direction and optical rotation. The helical structure is not an abstract concept but a substance and it has definite directional character and many characteristic parameters. The helical structure is just the essential reason resulting in the optical activity. The helical structure can be correlated with the rotatory direction and the value of optical rotation. The helix theory is not in contradiction with the chirality because the helix itself is chiral.
