LXIII.—The rotatory power of benzene-derivatives

Nonreciprocity of natural rotatory power.

We have observed that a light beam that passed through an optically active crystal of Bi(12)SiO(20) and that was then ref lected exactly back through it did not recover its initial polarization orientation. The nonreciprocal component of the rotation was of the order of 2 x 10(-3) of the reciprocal, single-pass rotation. This nonreciprocity is unambiguous evidence of broken reversality of the l...

The Optical Rotatory Power of Heat-denatured Egg Albumin

Atomic partition of the optical rotatory power of methylhydroperoxide.

We applied a methodology capable of resolving the optical rotatory power into atomic contributions. The individual atomic contributions to the optical rotatory power and molecular chirality of the methylhydroperoxide are obtained via a canonical transformation of the Hamiltonian by which the electric dipolar moment operator is transformed to the acceleration gauge formalism and the magnetic dip...

Optical rotatory power of polymer-stabilized blue phase liquid crystals

Macroscopically, a polymer-stabilized blue phase liquid crystal (BPLC) is assumed to be an optically isotropic medium. Our experiment challenges this assumption. Our results indicate that the optical rotatory power (ORP) of some nano-scale double-twist cylinders in a BPLC composite causes the polarization axis of the transmitted light to rotate a small angle, which in turn leaks through the cro...
