dichroism

(ˈdaɪkrəʊˌɪzəm)

1. (General Physics) Also called: dichromaticism a property of a uniaxial crystal, such as tourmaline, of showing a perceptible difference in colour when viewed along two different axes in transmitted white light. See also pleochroism

2. (Chemistry) a property of certain solutions as a result of which the wavelength (colour) of the light transmitted depends on the concentration of the solution and the length of the path of the light within the solution
