Optical Rotatory Dispersion1 Nature

Optical rotation is measured with an instrument called a polarimeter. There is a linear relationship between the observed rotation and the concentration of optically active compound in the sample. There is a nonlinear relationship between the observed rotation and the wavelength of light used. Specific rotation is calculated using either of two equations, depending on whether the sample is a pure chemical to be tested or that chemical dissolved in solution. WebA quantity defined for materials displaying optical activity as \hbox{[specific rotary power]} = {\beta\over d} = {\pi\over\lambda_0} (n_l-n_r), where \beta is the angle of rotation of linear polarization, d is the thickness of the medium, \lambda_0 is the vacuum wavelength, n_l is the index of refraction for parallel polarization, and n_r is the index of refraction for … WebPolarimetry utilizes the optical rotatory dispersion (also called optical activity) of the glucose molecule, which rotates the polarization plane of transmitted linearly polarized light in proportion to the optical path length and the glucose concentration.46 The optical rotation associated with typical physiological glucose concentrations is … sona home products
