Definition of Dichroism

1. Noun. Pleochroism of a crystal so that it exhibits two different colors when viewed from two different directions.

Generic synonyms: Pleochroism

Definition of Dichroism

1. n. The property of presenting different colors by transmitted light, when viewed in two different directions, the colors being unlike in the direction of unlike or unequal axes.

Medical Definition of Dichroism

1. Differential absorption of right hand and left hand circularly polarized light resulting from molecular asymmetry involving a chromophore group. Circular dichroism is used to study the conformation of proteins in solution. This entry appears with permission from the Dictionary of Cell and Molecular Biology (11 Mar 2008)
