Conversely, their absoluteconfiguration can be deduced from the optical rotation direction.
反之，由旋光方向可以推断其绝对构型。
2
The resolution of some chiral drugs such as d, L-dansyl amino acid has certain rule, and provides information about absoluteconfiguration.
对一些物质，如d, L丹酰化氨基酸的拆分有一定的规律，能给出绝对构型信息。

The determination of absoluteconfiguration for chiral compounds is one of the most important problem in the organic chemisty, especially for chiral drug synthesis.
