We have synthesized and separated the enantiomer pair of chiral cyclotrisiloxanes for the first time. Three-blade propeller-like alignment of three phenyl groups in tri(2-butyl)triphenylcyclotrisiloxane induced a positive Cotton effect with (R)-2-butyl group, and a negative effect with (S)-2-butyl substituent.

Chiral measure of chiral polyhedrons
ChiralityAbstractTo quantify chiral shape, a tensor describing the particle shape has been proposed. This tensor, named the shape tensor (S‐tensor), is an analog of the hydrodynamic tensor that relates the rotational and translational motions of particles in a liquid.

The most abundantly used route toward enantiopure chemical and biological products is through chiral separation of racemates. Several methods are available, of which crystallization is most used in industry, and chromatography is the most common analytical technique.

Chirality, 2005
A review of chiral, nanoscale science and technology is presented, with the subject divided into two topics. The first discusses nanotechnology in the service of asymmetric synthesis, chiral separations, and analysis. The second topic concerns broader research in the nanotechnology realm, where molecular chirality plays a role in the properties of ...

Summary: The theory distinguishing the molecular chirality in the optical transition is presented. The characteristic combination responsible for this transition is the angular momentum of molecule and the magnetic field produced by photons. The amplitude is so small estimated \(v/c\) times that of the dipole transition. The specified model employed is
