Optical rotation from Earth rotation?
Physics World, 1990Can the Earth's rotation affect atomic physics? Mark Silverman of Trinity College, Hartford, CT, USA suggests that the Earth's rotation could induce a detectable amount of optical rotation in atoms (1990 Phys. Lett. A 146 175). Optical rotation is the rotation of the plane of polarisation of a light beam about its direction as it passes through some ...

Optical Rotation of Achiral Compounds
Angewandte Chemie International Edition, 2008AbstractOriented achiral molecules and crystals with D2d symmetry or one of its nonâenantiomorphous subgroups, S4, C2v, or Cs, can rotate the plane of transmitted polarized light incident in a general direction. This wellâestablished fact of crystal optics is contrary to the teaching of optical activity to students of organic chemistry. This Minireview

The Journal of Chemical Physics, 1987
Optical activity generated by the rotational normal coordinates is investigated. The theoretical formulation is based on classical principles and uses the definition of the rotational normal coordinates and the changes in electric and magnetic dipole moment components along the principal axes of inertia due to rotations represented by these coordinates.

American Journal of Physics, 2010
Three calculations of optical Faraday rotation are presented in which a linearly polarized field is incident on a medium of harmonic oscillators in the presence of a longitudinal magnetic field. The rotation of the plane of polarization of the field is evaluated using classical oscillators and the Lorentz force equation, quantum oscillators and the ...

Optical Rotation of Achiral Pentaerythritol
Journal of the American Chemical Society, 2006The optical rotatory power of achiral crystals of achiral pentaerythritol molecules was measured. The maximum rotations were found to be +/-6 degrees /mm. The quantum mechanically computed rotation of pentaerythritol molecules using linear response theory was 6 times larger although the experimental and theoretical tensors were similarly oriented to ...

Nonreciprocal Optical Rotation in Antiferromagnets
Physical Review Letters, 1995We consider nonreciprocal optical effects in classical N\'eel antiferromagnets, where the purely macroscopic electrodynamics does not provide any rotation. The nonzero result appears as a correction linear in the scattering theory parameter $a/\ensuremath{\lambda}$, atomic distance over wavelength.

Optical Rotation of Noncovalent Aggregates
Journal of the American Chemical Society, 2003Dilute solutions of (R)-(-)-pantolactone in CCl4 were studied by polarimetry in conjunction with theoretical calculations of [alpha]D. Our data demonstrate that the self-association of a chiral solute results in a change in [alpha]D that can be accounted for by the presence of hydrogen-bonded dimeric species.

Fiber-optic rotation sensor technology
Applied Optics, 1980A concept for an all-waveguide fiber-optic rotation sensor is discussed, and the results of preliminary tests of key elements are described. A single channel waveguide coupler design provides the functions of an optical switch, a 3-dB beam splitter, a phase retarder, and a signal modulator, all of which may be formed on the same chip and interconnected

Nature, 1935
THE subject of the influence of magnetism on light has again been coming into experimental prominence, combined, however, with confusion on the side of theory: and a brief exposition of some considerations which I have treated more privately more than once may be to the public advantage.

OPTICAL ROTATION AND ATOMIC DIMENSION
Journal of the American Chemical Society, 1934AbstractFrom measurements of the optical rotations of F, Cl, Br, I substitutes of acetyl sugars and of optically active alcohols two rules are derived connecting the differences in optical rotation with the differences of atomic diameter.
