Measurement of nuclear-spin transitions and their chemical shifts, couplings, relaxation, and spatial encoding in a magnetic field.

This is an authored directed relation from the source endpoint to the target endpoint.
Chemical shifts, couplings, integrations, exchange, and multidimensional correlations can support a functional-group assignment, but values remain solvent-, temperature-, conformation-, and structure-dependent.
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.
wp-chem-organic-chemistryiupac-blue-bookpubchem-docsThis is an authored directed relation from the source endpoint to the target endpoint.
NMR is a molecular spectroscopy in which local electronic environments alter nuclear-spin resonance frequencies and couplings.
The target is a member or subtype of the broader source class.
wp-chem-quantum-chemistryiupac-green-booknist-chemistry-webbookThis is an authored directed relation from the source endpoint to the target endpoint.
Chemical shifts, scalar couplings, dipolar effects, and exchange behavior can support stereochemical assignments when conformational averaging and model ambiguity are assessed.
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.

This is an authored directed relation from the source endpoint to the target endpoint.
Bloch’s induction and Purcell’s absorption experiments detected coherent nuclear magnetic response and established complementary NMR methods.
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.
