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. WebOptical activity, or optical rotatory power, describes the phenomenon in which the polarization direction of a linearly polarized light wave rotates as the wave travels within the medium[42,60] Typical magnitudes of this effect range from 20° to 2000° per cm of path … data factory parse
