The "'electrogyration "'effect is the spatial dispersion phenomenon, that consists in the change of optical activity ( gyration ) of crystals by a constant or time-varying electric field.
42.
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 usually classified under " optical activity ."
43.
Measurements of vibrational optical activity ( VOA ) have thus numerous applications, not only for small molecules, but also for large and complex biopolymers such as muscle proteins ( myosin, for example ) and DNA.
44.
By scanning the microscope's beam in an X-Y pattern and measuring the light emitted with the beam at each point, a map of the optical activity of the specimen can be obtained ( cathodoluminescence imaging ).
45.
Chiral synthesis is built on a combination of stereospecific transformations ( for the interconversion of existing stereocenters ) and stereoselective ones ( for the creation of new stereocenters ), where also the optical activity of a chemical compound is preserved.
46.
;1873 : Jacobus Henricus van't Hoff and Joseph Achille Le Bel, working independently, develop a model of chemical bonding that explains the chirality experiments of Pasteur and provides a physical cause for optical activity in chiral compounds.
47.
His goal was to see if addition of the organic dye on the crystalline structure would induce " enhanced optical activity " ( rotation ) of light in the 500-600 nm absorption band on the otherwise optically inactive dye.
48.
On the other hand, amorphous forms of silica such as fused quartz, like a racemic mixture of chiral molecules, has no net optical activity since one or the other crystal structure does not dominate the substance's internal molecular structure.
49.
Changing the geometry of the nanoparticles can be used to manipulate the optical activity and properties of the system, but so can the polarized light by lowering the symmetry of the conductive electrons inside the particles and changing the dipole moment of the cluster.
50.
In 1874, Jacobus Henricus van't Hoff and Joseph Achille Le Bel independently proposed that the phenomenon of optical activity could be explained by assuming that the chemical bonds between carbon atoms and their neighbors were directed towards the corners of a regular tetrahedron.
