Inference of molecular energies, structures, populations, and dynamics from frequency-resolved interaction with radiation or particles.

This is an authored directed relation from the source endpoint to the target endpoint.
Crystal-field splittings help organize electronic spectra and magnetism, while covalency, spin–orbit coupling, and vibronic effects refine assignments.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
wp-chem-inorganic-chemistryiupac-red-bookiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
Electromagnetic radiation couples to molecular charge and current distributions, producing frequency-, polarization-, and geometry-dependent absorption, emission, or scattering measured in molecular spectroscopy.
The source field, particle, charge, current, or interaction couples to, acts on, binds, forms, or stabilizes the target in the stated regime. The edge label and detail must identify the exact coupling, interaction, or binding claim and its qualifications.

Resolved transition frequencies, intensities, splittings, and selection patterns test structural assignments, but extracting geometry or dynamics requires an explicit spectroscopic model and uncertainty analysis.
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.

Molecular symmetry classifies states and normal modes and constrains which transitions can carry intensity.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

This 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.
