For a long time, chemists have considered that there is no relationship between the optical activity of compounds under sodium D line (589 nm) and their stereostructure, and often took the optically active change of lactic acid and its derivatives (with the same configuration) as an example.
长期以来,化学家一直认为化合物在D线下的旋光性与其立体结构无关,并常以乳酸及其相同构型的衍生物的旋光性变化为例证。
