How this entity was disambiguated
This entity first appeared as the object of triple T6788461 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Jablonski diagram Context triple: [Stokes shift, relatedTo, Jablonski diagram]
-
A.
Franck–Condon principle
The Franck–Condon principle is a rule in molecular spectroscopy that explains the intensity distribution of vibronic transitions by assuming electronic transitions occur much faster than nuclear motion, making vertical transitions between vibrational states most probable.
-
B.
Huang–Rhys factor
The Huang–Rhys factor is a dimensionless parameter in solid-state and molecular spectroscopy that quantifies the strength of electron–phonon (vibronic) coupling during electronic transitions.
-
C.
Stokes shift
Stokes shift is a phenomenon in spectroscopy where the wavelength of emitted light is longer (lower energy) than that of the absorbed light, commonly observed in fluorescence and phosphorescence.
-
D.
Herzberg–Teller approximation
The Herzberg–Teller approximation is a refinement in molecular spectroscopy that accounts for vibronic coupling by allowing electronic transition dipole moments to depend on nuclear coordinates, explaining intensity in otherwise forbidden transitions.
-
E.
Feynman diagrams
Feynman diagrams are graphical representations used in quantum field theory to visualize and calculate particle interactions and processes.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
