The stereostructure can be predicted from the rotatory direction for simple compounds(for example S,R-Noscapine).

对单的化合物,通过旋光向可以推断其立体结构(例如S,R那可汀)。

The tetramisole molecular have optical activity.The traditional method is time and cost consuming to decide the rotatory direction and the value of optical rotatory.

咪唑分子具有光学活性，为了确定旋光度的大小和向，使用法既耗时又不经济。
