optical rotation

(optics)
Rotation of the plane of polarization of plane-polarized light, or of the major axis of the polarization ellipse of elliptically polarized light by transmission through a substance or medium.

For measurements, a film was fixed vertically in the rotating cell of the spectropolarimetric cuvette--that is, perpendicularly to the incident beam of polarized light--and its optical rotation spectrum was recorded.
Recording changes in optical rotation is another promising method to read stored information in a non-invasive manner because detection can be readily performed outside the photoactive spectral region, thereby reading without erasing the stored information.
Based on electron distributions, they predicted optical rotation for three classes of compounds: oxiranes, simple chiral molecules that are small and rigid; more complex cyclic esters; and linear molecules, specifically fluorohexane.
Optical rotations were measured at JASCO DIP-360 polarimeter (Tokyo, Japan).
Some cellulose derivatives like cellulose acetate, methyl cellulose or hydroxypropyl cellulose (HPC) present changes in the optical rotation with wavelength and solvent, the latter determining specific interactions in solutions [7-10].
The functionality of dual-band circular polarizer (giant CD effect) and linear polarization transformer (giant optical rotation) of the proposed asymmetric CMMs can be clearly demonstrated through the analysis of ellipticity ([eta]) and the polarization rotation angle ([theta]) described in detail in [3, 25].
The new Princeton method, dubbed nuclear-spin optical rotation (NSOR), enlists the use of a laser beam to measure how the nuclear spins within a sample rotate about the polarization plane of a beam.
