27 Feb 2018 The optical rotation angle normalized to the sample thickness was found to be several orders of magnitude larger than that in natural materials.

This organic chemistry video tutorial explains how to calculate the specific rotation of an enantiomer given the observed rotation, the pathlength, and the c

Vibrational Optical Activity: Principles and Applications. Författare. Laurence A. Nafie.

optical activity The ability of certain substances to rotate the plane of plane-polarized light as it passes through a crystal, liquid, or solution. It occurs when the molecules of the substance are asymmetric, so that they can exist in two different structural forms each being a mirror image of the other.

optinen rotaatio Enantiomers are isomers which show optical activity. If the (+) and (-) enantiomers are present in the same ratio in a crystal, then it is known as a racemate. Vibrational Optical Activity [Elektronisk resurs] Principles and Applications.

I am a theoretical condensed matter physicist and my main research activity is activities, I would like to mention nonlinear optical probing of collective modes

This is especially true at THz frequencies owing to the large mismatch of THz wavelengths (hundreds of micrometers) and characteristic dimensions of crystal lattices and molecules (about a nanometer). Since optical activity gives a compound the ability to rotate plane-polarized light, we can put a sample of the compound in between the polarizer and analyzer. This will rotate the light, allowing some of it to get through the analyzer even when the filters are at right angles (Figure 1-3).

Biot was studying the nature of plane‐polarized light (Figure 1) when he discovered that solutions of some organic compounds caused polarized light to rotate. Some liquids and solutions, when placed in the path pf plane-polarized light, rotate it through a certain angle.”The property of rotating plane-polarized light to the left or right is called optical activity and the substance is called the optical activity“.Those rotating in a clockwise direction are called dextrorotatory and those in anti-clock direction are called laevorotatory. Optical Activity Optical activity of an organic compound refers to the property of an organic compound by the virtue of which, it rotates the plane polarized light (produced by passing ordinary light through Nicol prism) when it is passed through their solutions and the compounds are known as optically active compounds. Since optical activity gives a compound the ability to rotate plane-polarized light, we can put a sample of the compound in between the polarizer and analyzer. This will rotate the light, allowing some of it to get through the analyzer even when the filters are at right angles (Figure 1-3). Optical activity is reciprocal, i.e. it is the same for opposite directions of wave propagation through an optically active medium, for example clockwise polarization rotation from the point of view of an observer.
