laue diagram
C2Technical/Scientific
Definition
Meaning
A photographic or digital image showing the diffraction pattern produced when X-rays are scattered by a crystal.
In crystallography, a specific type of diffraction pattern used to determine the symmetry and orientation of a crystal's lattice structure. The pattern consists of spots or arcs arranged symmetrically, providing information about the crystal's internal geometry.
Linguistics
Semantic Notes
This term is highly specialized and exclusively used in fields like crystallography, materials science, and solid-state physics. The phrase is a proper noun (named after Max von Laue) and is typically not used metaphorically. The plural is 'Laue diagrams' or 'Laue patterns'.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling conventions (e.g., centre/center) may apply in surrounding text but not to the term itself.
Connotations
Identical technical connotations in both varieties.
Frequency
Extremely low frequency in general language, identical frequency in relevant scientific communities in both the UK and US.

Usage
Context Usage
Business
Virtually never used.
Academic
Exclusively used in highly technical papers and lectures in crystallography, physics, chemistry, geology, and materials science.
Everyday
Never used in everyday conversation.

Examples
By Part of Speech
verb
British English
- The crystal was Laue-diagrammed to check its orientation.
American English
- They Laue-diagrammed the specimen prior to cutting.
adjective
British English
- The Laue-diagram analysis confirmed the crystal symmetry.
American English

Examples
By CEFR Level
- Scientists use special X-ray pictures called Laue diagrams to study crystals.

Learning
Memory Aids
Mnemonic
Think of 'Loud Diagram': A loud (pronounced like 'Laue') and clear diagram that shouts information about a crystal's structure.
Conceptual Metaphor
THE CRYSTAL'S FINGERPRINT (A Laue diagram is a unique identifier of a crystal's structure, just as a fingerprint identifies a person).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'Laue' (it's a proper name). Avoid кальки like 'диаграмма Лауэ' unless it's the established term in the specific Russian scientific subfield (диаграмма Лауэ is correct).
Common Mistakes
- Misspelling as 'Lou diagram', 'Lowe diagram', or 'Laue diagramm'. Incorrect capitalisation ('laue diagram'). Using it as a general term for any graph or chart.

Frequently Asked Questions
It is pronounced to rhyme with 'how' or 'now' (/'laʊə/).
Typically, no. Standard Laue diagrams require a single crystal to produce a clear spot pattern. Polycrystalline materials produce concentric rings (Debye-Scherrer rings).
Max von Laue, a German physicist who won the Nobel Prize in 1914 for his discovery of the diffraction of X-rays by crystals.
No, it is a highly specialized technical term used only in specific scientific fields like crystallography and materials science.
