Such optical activity due to extrinsic chirality was observed in the 1960s in liquid crystals. [28] [29] In 1950, Sergey Vavilov [30] predicted optical activity that depends on the intensity of light and the effect of nonlinear optical activity was observed in 1979 in lithium iodate crystals. [31] Optical activity is normally observed for ...
Chiral resolution, or enantiomeric resolution, [1] is a process in stereochemistry for the separation of racemic mixture into their enantiomers. [2] It is an important tool in the production of optically active compounds, including drugs. [3]

The foundation of Cooke Optics is coincident with Taylor, Taylor and Hobson (TTH) in 1886, as the sole activity of TTH was the manufacture of lenses under the Cooke branding. Administratively speaking, Cooke Optics is a spin-off of Taylor-Hobson, created after Taylor-Hobson shifted its focus to metrology instruments.
Bunn [8] predicted in 1945 that extrinsic 3d chirality would cause optical activity and the effect was later detected in liquid crystals. [9] [10] Extrinsic 3d chirality causes large optical activity and linear conversion dichroism in metamaterials. These effects are inherently tuneable by changing the relative orientation of incident wave and ...
Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. [ 1 ] Electro-optics is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields , whether or not they form part of an ...

The effects due to solvent on stabilizing the structures (conformers and zwitterionic species) of amino acids and peptides and the corresponding effects seen in the vibrational circular dichroism (VCD) and Raman optical activity spectra (ROA) have been recently documented by a combined theoretical and experimental work on L-alanine and N-acetyl ...
