The concept of optical rotation, also known as specific rotation or rotatory power, describes the ability of a substance to rotate the plane of polarized light. This phenomenon, measured in terms of degrees of rotation, is influenced by the chemical composition, concentration, and the length of the path that the light travels through the substance. In the field of chemistry and pharmaceuticals, optical rotation plays a crucial role in determining the purity, identity, and concentration of chiral compounds. In scientific literature and research, a plethora of English short sentences and example sentences showcasing the application and significance of optical rotation can be found. These sentences cover a wide range of topics including fundamental principles, experimental techniques, and practical applications, providing a comprehensive understanding of this optical property.

旋光度分子式：CAS号：性质：又称旋光率，比旋光度。平面偏振光通过含有某些光学活性的化合物液体或溶液时，能引起旋光现象，使偏振光的平面向左或向右旋转(按顺时针方向转动称为右旋，用“+”表示；按逆时针方向转动称为左旋，用“-”表示)。旋光仪是用来测定光学活性物质旋光能力大小和方向的仪器。光学活性物质可以旋转偏振光平面，其大小和方向除了与该物质结构有关外，还与测定时的温度、所用光的波长、溶液的浓度和溶剂、旋光管的长度等有关。一般单色光源用钠光灯，波长为589nm，以D表示。规定以每毫升溶液所含溶质的克数作为质量浓度的单位。由旋光仪测得旋光角度后，可以下式计算旋光度：式中，α为用旋光仪测得的旋光度；c为溶液的质量浓度(g/ml)；l为旋光管的长度/dm；t为测定时温度(℃)，λ为测定所用光波波长(钠光以D表示)。光活性物质为液体时，则以密度ρ(g/ml)代替c，即若以100ml溶液含溶质的克数，则，如果糖的水溶液，溶液浓度为5g/100ml，在1dm旋光管中测得旋光角度为-4.64°，则：书写旋光度时，除注明温度，光波波长外，在数据后的括号内，注明其质量百分浓度和配制溶液用的溶剂。
