Summary

Measurement of transitions among rotational states, often in the microwave or millimetre-wave region, yielding moments of inertia and precise molecular constants.

Incoming relations (arrows to this concept)

Each relation below ends at this concept.

Molecular rotationRotational spectroscopy

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

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.

How to interpret this relation type

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.

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Rotational spectroscopy resolves transitions dominated by molecular rotation.

How to interpret this relation type

The target is a member or subtype of the broader source class.

Rotational spectroscopyMolecular geometry

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Rotational constants constrain principal moments of inertia and isotopic substitution can support geometry determination.

How to interpret this relation type

A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
