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

对于较简单的化合物,通过旋光方向以推断其立体结构(例如S,R)。

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.

子具有光学活性，为了确定旋光度的大小和方向，使用传统方法既耗时又不经济。
