Optical rotation is the turning of the plane of linearly
polarized light about the direction of motion as the light
travels through certain materials. It means it is only a
measure of degree of polarised light.
But Specific optical rptation is the observed angle of
optical rotation (α) when plane-polarized light is passed
through a sample with a path length of 1 decimeter and a
sample concentration of 1 gram per 1 millilitre
optical rotaion(α)
Specific optical rotation = -------------------
path length in decimeters x C
C = concentration in g/ml
The specific optical rotation is Temperature dependent and
also it depends on wavelength of light used for measurement
Generally the sodium D line is used at 589 nm for
measurement.
