WebOptical rotation is a function of time and it is used to determine kinetic reactions This is also used to plot optical rotatory dispersion curves for a various range of wavelengths this helps in analysing molecular structure The optical rotation is measured on a layer of suitable thickness at the wavelength specified in the monograph. WebThe optical rotation on the polarimeter was 66 degrees Celsius, in a positive reaction. The unknown solvent is most likely a (+)-α-pinene, as the positive light signifies a positive enantiomer. ... they decide to set up a vacuum distillation of eugenol (boiling point = 254 °C at 760 mmHg) in the back of the Wells Fargo Center.
