Definition
- Adjective:
- Having the same or similar crystalline form: In chemistry and mineralogy, describes substances that crystallize in the same form despite having different chemical compositions.
- Having a similar structure or form: More broadly, it can describe things that are alike in shape or structure.
- Being isomorphic: In mathematics, it describes a one-to-one correspondence that preserves structure between two mathematical sets or systems.
Usage Examples
- Adjective:
- Calcite and aragonite are isomorphous minerals; they share the same crystal shape but have different chemical formulas.
- The two software programs have an isomorphous architecture, making them easy to learn in tandem.
- In abstract algebra, these two groups are isomorphous, meaning their structures are essentially the same.
Advanced Usage
- "Isomorphous replacement": A technique in X-ray crystallography used to determine the structure of molecules.
- Scientists used isomorphous replacement to solve the protein's three-dimensional structure.
- "Isomorphous series": A series of compounds that have similar crystalline forms.
- The plagioclase feldspars form an isomorphous series between albite and anorthite.
Variants and Related Words
- Isomorphism (n): The condition of being isomorphous; a one-to-one structure-preserving mapping.
- The isomorphism between the two graphs was proven.
- Isomorphic (adj): A more common variant with the same meaning as "isomorphous".
- The two networks are isomorphic.
Synonyms
- Isostructural: Having an identical or very similar crystal structure.
- Congruent: Coinciding exactly when superimposed; often used in geometry.
- Analogous: Similar or comparable in certain respects.
Antonyms
- Polymorphous: Having, assuming, or occurring in various forms, shapes, or crystals.
- Heteromorphous: Differing in form or structure.
Related Phrases
- "Exhibit isomorphism": To display a shared form or structure.
