In science:

The thick (250 micron) film samples were used for the optical rotatory power (ORP) measurements, in which a standard setup was used where the analyzer is rotated against the polarizer to obtain a minimum of the light (630 nm) transmission.
General phase diagram for antiferroelectric liquid crystals in dependence on enantiomeric excess
In particular, we give explicit and closed results for the rotatory power, the electric-dipole-electric-dipole polarizability, and the electricdipole-electric-quadrupole polarizability, both at imaginary frequencies.
The twisted arc model for chiral molecules
Based on these results the rotatory strength is calculated in Sect. 4, as a function of the chiral angle.
The twisted arc model for chiral molecules
We proceed with the discussion of the rotatory strength, the most prominent property of chiral molecules.
The twisted arc model for chiral molecules
The trace of the optical rotatory tensor yields the rotatory strength, zz = Im nD1|−→d |nE · Dn|−→m |1Eo .
The twisted arc model for chiral molecules
We note also that the rotatory strength does not depend on the choice of origin.
The twisted arc model for chiral molecules
As one expects, the rotatory strength is antisymmetric with respect to the twist angle, and the sum rule (36) for the rotatory strength is fulfilled.
The twisted arc model for chiral molecules
Having found reasonable choices for the parameters L and Zeff , we now proceed to evaluate the frequency dependent rotatory power G′ (ω ), a further quantity which permits a comparison with the literature values of the real molecule H2S2 .
The twisted arc model for chiral molecules
The polarizability, given in atomic units, scales as Z 2 eff L3 , where a factor Z 2 eff L is contributed by the dimensions of the rotatory tensor and a factor L2 by the decrease of the excitation energy with increasing length scale.
The twisted arc model for chiral molecules
The derived chiral properties, such as the rotatory strength and the dispersive interaction potentials, thus display a simple, while physically consistent dependence on the model parameters.
The twisted arc model for chiral molecules
The orthogonal transformation is called rotation if det α = 1 and rotatory reflection if det α = −1.
From Ginzburg-Landau to Hilbert-Einstein via Yamabe
Let Cn be a rotation which corresponds to the angle 2π/n, then a rotatory reflection is given by Sn = σ ◦ Cn , i.e. it is a superposition of a rotation followed by reflection σ (rotation by the π angle) in the plane perpendicular to the axis of rotation.
From Ginzburg-Landau to Hilbert-Einstein via Yamabe
The group G(P ) generally contains both proper and improper isometries, that is, rotations, and plane reflections or rotatory reflections.

In particular, σ 2 p or q is odd, then σ1 ∈ G(P ) or σ2 ∈ G(P ), respectively; in fact, in this case we even have σ1 ∈ G+ (P ) or σ2 ∈ G+ (P ), respectively, since elements of G(P ) not in G+ (P ) are necessarily reflections or rotatory reflections and hence have even period.
