Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.
Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.
Measurement of transitions among rotational states, often in the microwave or millimetre-wave region, yielding moments of inertia and precise molecular constants.
rotational-state structure tested by resolved spectra
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.

constrains moments of inertia
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.
