1. The rotation of the plane of polarized light in a clockwise direction when viewed by an observer looking toward the light source; rotation to the right.
Usage: chemistry; physics; technical

Examples

• The dextrorotation of the sugar solution was measured using a polarimeter.
• Dextrorotation indicates that the compound rotates polarized light to the right.
• The chemist observed dextrorotation in the glucose sample.
• Dextrorotation and levorotation are opposite optical properties.
• The degree of dextrorotation depends on the concentration and wavelength of light used.
