đối quang
Definition
- Noun:
- Enantiomorph: In chemistry and crystallography, a crystal form that is the mirror image of another and cannot be superposed on it, much like left and right hands. This term describes a pair of chiral molecules or crystals that are non-superimposable mirror images of each other.
Usage Examples
- Noun:
- Hai dạng tinh thể này là đối quang của nhau. (These two crystal forms are enantiomorphs of each other.)
- Phân tử này có một đối quang. (This molecule has an enantiomorph.)
Advanced Usage
- In stereochemistry, the concept of đối quang is fundamental to understanding chirality and optical activity. Enantiomers, a type of đối quang, often have identical physical properties but differ in how they rotate plane-polarized light and interact with other chiral molecules.
Variants and Related Words
Chất đối quang (n): enantiomer. Refers specifically to one of a pair of chiral molecules.
- Chất đối quang này quay mặt phẳng ánh sáng sang trái. (This enantiomer rotates the plane of light to the left.)
Tính đối quang (n): chirality; the property of having a non-superimposable mirror image.
- Tính đối quang rất quan trọng trong dược phẩm. (Chirality is very important in pharmaceuticals.)
Synonyms
- Enantiomer: (In chemical context) One of a pair of chiral molecules that are mirror images.
- Optical antipode: An older term for an enantiomer.
- Mirror-image form: A descriptive synonym for an enantiomorph.
