For example, the specific rotation of sucrose at 20°C for the sodium D line is expressed as = 66.5°. (2) The amount obtained by multiplying the specific rotation [α] λ t by the molecular weight M of an optically active substance is called the molecular rotation power, or molar rotation power, and is the angle of rotation shown by a 1 m liquid layer of a solution containing 1 mol of an optically active substance in 1000 cc of solution, and is a convenient amount for comparing the inherent optical rotation of molecules. (3) The optical rotation of a crystal is usually expressed as the angle of rotation for a layer 1 mm thick. *Some of the terminology that refers to "molar rotary power" is listed below.
