Optical 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. … Se mer Dextrorotation and laevorotation (also spelled levorotation) are terms used in chemistry and physics to describe the optical rotation of plane-polarized light. From the point of view of the observer, dextrorotation refers … Se mer Optical activity occurs due to molecules dissolved in a fluid or due to the fluid itself only if the molecules are one of two (or more) stereoisomers; this is known as an enantiomer. The structure of such a molecule is such that it is not identical to its Se mer Rotation of light's plane of polarization may also occur through the Faraday effect which involves a static magnetic field. However, this is a distinct phenomenon that is not classified as "optical activity." Optical activity is reciprocal, i.e. it is the same for opposite directions of … Se mer • Eugene Hecht, Optics, 3rd Ed., Addison-Wesley, 1998, ISBN 0-201-30425-2 • Akhlesh Lakhtakia, Beltrami Fields in Chiral Media, World Scientific, Singapore, 1994 • A step by step tutorial on Optical Rotation Se mer The rotation of the orientation of linearly polarized light was first observed in 1811 in quartz by French physicist François Arago. In 1820, the English astronomer Sir John F.W. Herschel discovered … Se mer For a pure substance in solution, if the color and path length are fixed and the specific rotation is known, the observed rotation can be used to calculate the concentration. This … Se mer • Cryptochirality • Specific rotation • Circular dichroism Se mer Nettet5. okt. 2016 · Abstract. The phenomenon of molecular optical activity manifests itself as the rotation of the plane of linear polarization when light passes through chiral media. Measurements of optical activity and its wavelength dependence, that is, optical rotatory dispersion, can reveal information about intricate properties of molecules, such as the ...

By probing them with coherent optical states (weak laser pulses) of different amplitudes and measuring the quantum fluctuations of the output electromagnetic field, we determine how these black boxes would affect any arbitrary state of light within a practically relevant subspace of the optical Hilbert space.
