Dextrorotatory and levorotatory are terms used to describe the direction in which plane-polarized light is rotated by enantiomers. Dextrorotatory compounds rotate the plane of polarized light in a clockwise direction, while levorotatory compounds rotate it in a counterclockwise direction.

Dextrorotation and laevorotation (also spelled levorotation) [1][2] in chemistry and physics are the optical rotation of plane-polarized light. From the point of view of the observer, dextrorotation refers to clockwise or right-handed rotation, and laevorotation refers to counterclockwise or left-handed rotation. [3][4]

2022年2月28日 · An optically active compound that rotates the plane of plane-polarized light counterclockwise, observed toward the light leaving the compound, is said to be levorotatory (symbol: l or -) eg: (R)–Lactic acid: (1) is levorotatory. see also dextrorotatory

2023年10月22日 · If a compound rotates plane polarized light in the clockwise (+) direction, it is said to be dextrorotatory, while if it rotates light in the counterclockwise (-) direction it is levorotatory.

The meaning of LEVOROTATORY is turning toward the left or counterclockwise; specifically : rotating the plane of polarization of light to the left.

The observed rotations (\(\alpha\)) of enantiomers are opposite in direction. One enantiomer will rotate polarized light in a clockwise direction, termed dextrorotatory or (+), and its mirror-image partner in a counter-clockwise manner, termed levorotatory or (–).

Levorotatory Optical Activity. Direction: When seen along the direction of light propagation, levorotatory compounds rotate plane-polarized light in a counterclockwise direction. Usually, scientists indicate this rotation with a negative angle, such as -10 degrees.

2023年11月1日 · Levorotatory compounds are characterized by their ability to rotate plane-polarized light counterclockwise when viewed from the receiver. Dextrorotatory compounds, however, rotate plane-polarized light clockwise.

Levorotatory refers to the ability of a chiral molecule to rotate the plane of polarized light in a counterclockwise direction when viewed from the direction of the light source. This property is closely related to the concepts of optical activity, enantiomers, and …

levorotatory (of a crystal, liquid or solution) having the property of rotating a plane of polarized light to the left (e.g. fructose). Compare DEXTROROTATORY.
