Optical Activity of Racemic Mixtures With Limonene
Description: A sample of S-(+)- limonene is placed in a large cuvette glass made for this experiment and placed between two polarizers on an overhead projector. the optical activity is noted by the prismatic effect that occurs while changing the relative position of the two polarizers filter lines.
