补充资料：圆二色光谱
分子式：
CAS号：

性质：用于推断非对称分子的构型和构象的一种旋光光谱。光学活性物质对组成平面偏振光的左旋和右旋圆偏振光的吸收系数(ε)是不相等的，εL≠εR，即具有圆二色性。如果以不同波长的平面偏振光的波长λ为横坐标，以吸收系数之差Δε=εL­εR为纵坐标作图，得到的图谱即是圆二色光谱，简称CD。如果某手性化合物在紫外可见区域有吸收，就可以得到具有特征的圆二色光谱。由于εL≠εR，透射光不再是平面偏振光，而是椭圆偏振光，摩尔椭圆度[θ]与Δε的关系为：[θ]=3300Δε。圆二色谱也可以摩尔椭圆度为纵坐标，以波长为横坐标作图。由于△ε有正值和负值之分，所以圆二色谱也有呈峰的正性圆二色谱和呈谷的负性圆二色谱。在紫外可见光区域测定圆二色谱与旋光谱，其目的是推断有机化合物的构型和构象。
