Definition

C1Chemistry

(technical, academic)The ability of a substance, particularly chiral compounds, to rotate the plane of polarized light either to the left or right.

Example

  • The optical activity of the compound was measured using a polarimeter.
  • Chiral molecules exhibit optical activity due to their asymmetric structure.

C1Physics

(technical, academic)A property caused by asymmetrical molecular or crystal structure that enables a compound or crystal to rotate the plane of incident polarized light.

Example

  • The crystal's optical activity was evident when polarized light passed through it.
