Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Franck–Condon principle | Statement: [Herzberg–Teller approximation, refines, Franck–Condon principle]

Target entity: Franck–Condon principle
Context triple: [Herzberg–Teller approximation, refines, Franck–Condon principle]

• A. Franck–Condon principle chosen
  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. Born–Oppenheimer approximation
  The Born–Oppenheimer approximation is a fundamental method in molecular quantum mechanics that simplifies calculations by treating nuclear motion as much slower than electronic motion, allowing their behaviors to be separated.
• C. 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.
• D. Stark effect
  The Stark effect is the splitting and shifting of atomic or molecular spectral lines caused by an external electric field.
• E. 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.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
