Optical activity is measured by a polarimeter, and is dependent on several factors: concentration of the sample, temperature, length of the sample tube or cell, and wavelength of the light passing through the sample. Rotation is given in +/- degrees, depending on whether the sample has d- (positive) or l- (negative) enantiomers. The intensity of optical activity is expressed in terms of a quantity, called specific rotation, defined by an equation that relates the angle through which the plane is rotated, the length of the light path through the sample, and the density of the sample (or its concentration if it is present in a solution). A 50:50 mixture of enantiomers has no observable optical activity.

Optical rotation results from circular birefringence, i.e., from a difference between the indices of refraction for right and left circularly polarized light, n, and n,. possible to invert the above equations, i.e., to determine the X, from the measurements of [8(h)].

Optical activity definition - Optically active substances or molecules rotate plane of polarization of plane polarized light either in clockwise or in anticlockwise direction. This is called optical rotation and this phenomenon is called optical activity.

Optical Activity. Optical activity is the ability of a chiral molecule to rotate the plane of plane-polairsed light, measured using a polarimeter.A simple polarimeter consists of a light source, polarising lens, sample tube and analysing lens.

I 2018-05-23 · 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. In the Faraday effect, the asymmetry is due to magnetic field that is the same all over many molecules. In ordinary optical activity, the asymmetry is just molecular. Although the molecules are oriented randomly, their chirality will manifest in their interaction with light.
