Inference of periodic electron density and atomic structure from X-ray diffraction intensities, a structural model, and refinement against measured data.
wp-chem-analytical-chemistryiupac-orange-booknist-chemistry-webbookEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Crystallography infers atomic arrangements from reciprocal-space intensities and a constrained structural model.
The target is a member or subtype of the broader source class.
wp-chem-analytical-chemistryiupac-orange-booknist-chemistry-webbookThis is an authored directed relation from the source endpoint to the target endpoint.
Bragg’s relation and early structure solutions made crystal diffraction an operational atomic-structure method.
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
wp-chem-bragg-lawnobel-bragg-1915This is an authored directed relation from the source endpoint to the target endpoint.
A crystal-structure model is tested against diffraction intensities and refinement diagnostics; disorder, twinning, finite resolution, model bias, and phase information limit interpretation.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
