Optical activity

WebOptical activity of a molecule is defined as its ability to rotate a plane-polarized (light vibrating in one direction) light that passes through it. Optical activity of a molecule depends on the chirality of the molecule. A chiral molecule is a molecule that is a chiral carbon, i.e., a carbon with four different groups attached to it. WebThe optical activity is also influenced by the temperature, the wavelength of the light and the length of the optical path – the longer the path of the light through an optically active substance, the greater the angle of rotation. In addition, the concentration of the substance and the type of solvent are important for the measurement.
