补充资料：旋光性
| 旋光性 optical activity 线偏振光在某些物质中传播时其振动面发生旋转的性质。有些晶体如石英、辰砂等具有旋光性，称为旋光晶体。迎着光线方向看，振动面顺时针旋转的称为右旋，逆时针旋转的称为左旋。许多旋光物质同时存在右旋和左旋两类，分别称为右旋物质和左旋物质，它们具有相同的分子式，例如石英分右旋石英和左旋石英两种。实验表明，光通过旋光晶体后，振动面转过的角度ψ与晶体厚度i成正比，即  a称为旋光率，它与物质性质及波长有关，这一关系称旋光色散。若同种物质存在右旋和左旋两种旋光异构物，则它们的旋光率大小相等，只是旋转方向相反。除旋光晶体外，许多有机液体或有机物溶液均有旋光性，如松节油、醣类的水溶液等。实验表明，振动面转过的角度ψ与光在溶液中通过的长度l和溶液的浓度C成正比，即 [a]称为溶液的比旋光率。利用此规律可测定溶液的浓度 ，量糖计就是根据旋光原理设计的常见测量仪器。本来不具有旋光性的物质，在加纵向外磁场（磁场方向与光的传播方向平行或反平行）后，会产生旋光性，此即磁致旋光效应或法拉第效应。 |
