WebNext, the sample whose optical activity is to be measured is placed in the light beam. The number of degrees athat the analyzer must be turned to reestab-lish the dark field is the optical rotation of the sample. If the sample rotates the plane of po-larized light in the clockwise direction, the optical rotation is given a plus sign. Such a sam-
