关于分子旋光性的经典理论
On the classical theory of molecular optical activity
摘要：
讨论了分子旋光性的经典和半经典理论的基本原理。这些理论适用于光学活性有机分子的稀溶液。它表明，所有已知的现象在经典理论的分子旋光性可以描述与使用一个赝标量，这是一个统一的函数的入射光频率$ω$。旋光度和圆二色性之间的关系是从基本的Kramers-Kronig关系导出的。在讨论分子旋光性的一般理论时，我们引入了分子旋光性张量。结果表明，要计算任意频率的旋光度和圆二色性，只需要知道9个（3 + 6）分子张量。对分子旋光性的量子（或半经典）理论也作了简要的讨论。我们还提出了在真空紫外区，即$λ\le 150$ $nm$的波长处测量旋光度和圆二色性的可能性。
英文摘要：
The basic principles of classical and semi-classical theories of molecular optical activity are discussed. These theories are valid for dilute solutions of optically active organic molecules. It is shown that all phenomena known in the classical theory of molecular optical activity can be described with the use of one pseudo-scalar which is a uniform function of the incident light frequency $ω$. The relation between optical rotation and circular dichroism is derived from the basic Kramers-Kronig relations. In our discussion of the general theory of molecular optical activity we introduce the tensor of molecular optical activity. It is shown that to evaluate the optical rotation and circular dichroism at arbitrary frequencies one needs to know only nine (3 + 6) molecular tensors. The quantum (or semi-classical) theory of molecular optical activity is also briefly discussed. We also raise the possibility of measuring the optical rotation and circular dichroism at wavelengths which correspond to the vacuum ultraviolet region, i.e. for $λ\le 150$ $nm$.
