Overall rotational motion of a molecule, quantized for isolated molecules and coupled to vibration and electronic angular momentum.

This is an authored directed relation from the source endpoint to the target endpoint.
An isolated molecule has rotational degrees of freedom whose quantized level pattern depends on nuclear geometry and masses; symmetry, vibration–rotation coupling, fields, collisions, and condensed environments modify the ideal rigid-rotor description.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

This is an authored directed relation from the source endpoint to the target endpoint.
Resolved rotational transitions test a molecular rotational-level model and its moments of inertia, subject to selection rules, centrifugal distortion, state mixing, temperature, and isotopic composition.
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.
