Optical rotatory dispersion 意味
WebThe variance of specific rotation with wavelength—a phenomenon known as optical rotatory dispersion—can be used to find the absolute configuration of a molecule. [3] : 124 The concentration of bulk sugar solutions is sometimes determined by comparison of the observed optical rotation with the known specific rotation. WebOptical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.Optical activity occurs only in chiral materials, those …
