TLDR
In this paper, it is shown that optical rotation is a convenient method for studying the intramolecular stereolability in pentacoordinated species, particularly phosphorus derivatives, and that it can be used to obtain a more accurate color image.Abstract:
The purpose of this paper is to show that optical rotation is a convenient method for studying the intramolecular stereolability in pentacoordinated species, particularly phosphorus derivatives. In chemistry, it is difficult to present a completely new idea and we will deal with this topic under several headings.read more

TL;DR: In this article, the topological analysis of chiral molecular models has been extended to deal with organic-chemical conformations, and, on the other hand, with inorganic-chemical configurations to ligancy six.
